The AirForce top hat

by Tom Gaylord, a.k.a. B.B. Pelletier

This report was requested by blog reader Rob 8T2 and seconded by a number of others. I reported on the spring piston forward spring guide that’s known as a top hat, and he wondered if I was also going to talk about the AirForce top hat. Though they share the same name, the two items aren’t connected in any way. One is a spring guide, and the other is an adjustable valve stem for a pneumatic valve. The adjustable valve stem draws its name because, like the forward spring guide, it also looks like a gentleman’s top hat in profile.

AirForce Airguns old top hat
The sliding breech cover has been pushed forward, cocking the striker and revealing the breech for loading. This is the original valve from a first-generation AirForce Talon without a power adjustment wheel.

To understand the AirForce top hat, we have to go back in time to before AirForce Airguns air rifles had power adjustment wheels on the left side. In January 2000, I reported on the new AirForce Talon, the first air rifle to be offered to the U.S. market by the new AirForce company. But I’d already owned the rifle I tested for two years. I bought it from the UK company, GunPower, in 1998, when it was configured differently and sold as their Stealth rifle. In late 1999, AirForce Airguns sent the parts to reconfigure my rifle to their new Talon specification, with an 18-inch .22-caliber barrel.

By that time, I already had many hours of testing and shooting on the rifle in its original Stealth configuration with its 12-inch barrel. It was during that time, by talking to AirForce owner and creator John McCaslin, that I learned how to adjust the top hat of my rifle to change the power.

You may find it amazing to learn that I could adjust that rifle to fire from 65 f.p.s. all the way up to 950 f.p.s. with 14.5-grain Eley Wasps. In truth, any velocity below about 400 f.p.s. was just a parlor trick. The rifle could do it, but all consistency was lost. From 400 to 950, though, it was fairly consistent.

How the top hat power adjustment worked
Power was adjusted by screwing in the top hat to shorten the valve stroke and the valve dwell time (the time the valve stayed open). The valve stroke became shorter because the wide flange at the base of the top hat contacted the top of the valve body and stopped moving. Then, the valve return spring started pushing the valve stem closed again, aided by the high-pressure air inside the reservoir.

Conversely, a longer valve stroke meant more dwell time and more air flowing out. At some point, however, the pellet left the 18-inch barrel, and the longer valve stroke stopped having any additional influence. Once the pellet’s out of the barrel, no amount of additional air can push it any faster.

To loosen the top hat for adjustment, unscrew a tiny 0.050″ Allen screw in the large knurled bottom flange of the hat, allowing it to turn on its threads. Once the desired clearance was reached, the small screw was tightened again. This screw caused problems because enthusiastic owners were over-tightening it, causing it to put dents in the hollow valve stem it contacted. In later years, AirForce started putting two screws in this flange to increase the locking pressure and hopefully reduce the damage to the valve stem.

The o-ring secret
Adjusting the top hat was a chore. One day, airgunsmith Tim McMurray told me about an easier, more convenient way. He said to slip a rubber o-ring around the top hat flange, so it rode in the space beneath the flange. It very effectively limited the amount of valve stem travel. Once I found out how good it was, I left it in place all the time. I wasn’t interested in sheer velocity. I wanted good accuracy at a reasonable level of power. Nothing has changed in 14 years, has it?

AirForce Airguns Talon SS top hat
The closed breech of this very early Talon shows where the o-ring goes.

Here you see the breech open for loading.

Talon SS puts an end to top hat adjustment
In November 2000, I wrote about the new Talon SS, which was the first AirForce rifle to have a power adjuster on the left side of the gun. My own SS was a pre-production prototype that didn’t have the power scale engraved on the side of the rifle; but after 14 years of continuous use, it’s still working fine and the air tank has never leaked.

AirForce Airguns Talon SS power adjuster
All AirForce sporting PCPs now have this power adjustment wheel.

The Talon was also updated with the power adjustment wheel at the same time. Now all AirForce sporting PCPs have power wheels and the top hats no longer need adjustment.

John thought that the power-adjustment mechanism would put an end to the fiddly top-hat adjustment, but it didn’t! By the time the power adjuster came on the market, there was a lot of interest in AirForce Airguns…and the internet was abuzz with homebrew ideas of how they should be set up and operated. People did use the new adjustment, but they also continued adjusting their top hats. Top hats continue to be adjusted and discussed right down to today!

The truth about the top hat
The truth is that the top hat is still a very influential part of the AirForce system. It does have tremendous impact on the rifle’s operation, though not always in the ways you read on the internet. Now that the rifles have the power adjustment wheel, the top hat has become more of a starting point or a setting that gives each rifle a potential range of power. The power adjustment wheel is what fine-tunes that range. The top hat is a set-and-forget kind of adjustment, only people are not leaving it alone.

Some valve stems are very thin, such as those found on the Hi-Flo valves. When the screws are over-tightened on these valves, they dimple all too easily. That’s one reason I advise owners not to adjust their top hats.

Top hats are set at the factory with feeler gauges. I’ve told several people I once discovered that an American quarter coin was exactly the right thickness to set the top hat for a Condor Hi-Flo valve. I’ve actually done that more than once. A difference of one or two thousandths of an inch from the factory spec usually isn’t critical. But when the difference grows larger than that, it does start to become critical. It depends on which rifle you’re talking about to determine if the difference is critical.

For the record, I left AirForce Airguns in 2005, and a lot of things have changed since then. I’m not qualified to give out factory specs on anything they make today. I don’t adjust my top hats at all. I use the power adjuster 100 percent of the time when I adjust, and most of the time I leave each gun set at the position that gives me the greatest accuracy.

You wanted to know about the AirForce top hat — there you go.

    I did the o-ring behind the top hat trick within the first 3 days of getting my .177 cal. Talon SS.

    Some times its just too hard to leave these airguns alone if you know what I mean. ;)

    Then out came the .177 barrel and in went the .25 cal. barrel. And I remember I said I was going to leave this gun alone; no mods, just shoot and enjoy it. Yea right. I ain’t never left anything alone in my life. :)

      Well, nothing’s ever perfect! this means there’s always room for improvement.When I started working in an auto repair shop, with other techs, I marveled at some of the simple solutions some were using to address both age old problems and new ones! “Javier” might not be able to tie his shoes, but he fills tubing with sand before applying heat to bend it, this may not stop the pipe from kinking, but makes it much easier to control, While “Ed” cuts a tab out from under someone’s dash to aid heater core replacement, saving himself 1.5 hours-that’s $30 in his pocket! ” It was just there for the assembly line robot to hold it by during installation.”
      Once again, I find myself in a sea of knowledge.

        Or that tab was there so the dash would behave in a certain way when the airbag fired.
        I am not saying it was in the case, but unless you know exactly what all the outcomes of that kind of modification are don’t do it. Obviously the risks in some fields are higher than in others.

        B.B is right with sometimes things should just be left alone.

          Or on a 1970′s Buick Skylark with a V-8, drilling a hole in the fender well enabled one to access the rear spark plug fairly easily. I originally used 18″ of extensions and two universals on my socket for that little bugger. I found that no one had ever replaced it and the electrodes had eroded down to “safety pin” sized pieces of metal.

            You wouldn’t believe how big that book would be if somebody wrote about the tricks used in the muscle car days. Engines, suspension and so on. I’m not only talking about everyday maintenance or repairs. I’m talking performance tricks also.

            Its a shame that alot of those tricks wont get to be learned by generations to come. You know the tricks of the day could still be applied to the new vehicles that will becoming out.

            I actually would like to see what the hybrid cars will bring in terms of performance. How about a 60 mpg turbocharged 4 cyl. with electric assist that runs the 1/4 mile in the 12′s. Maybe I’m dream’n. But maybe not.

            • Reb Says:

              That’s exactly what my plan was with my last car! A ’97 Probe. It was slow off the line so I figured a couple of 5-10hp dc motors, one for each rear wheel and battery pack under the hatch. Naturally aspirated, that car would do 130mph all day!
              Alas, it disappeared while in storage, along with my beloved slavia 618.
              Sure do miss that lil’ gun!

  • RidgeRunner Says:

    It is real difficult to not fiddle with these things. Right now I am wanting to get an 18″ .25 barrel for my TSS and machine it to 16″. I was going to go .30, but I decided to wait until larger selection of pellets are available.

    I’m going to put a 12″ reservoir on my Edge also. That will probably increase the shot count significantly.

    Tinker, tinker, tinker, tinker…

      RR,

      By cutting back your barrel you will be cutting off the choke, unless you work from the breech end.

      B.B.

      • Joe Says:

        B.B.,
        Is a choked barrel really more accurate than a non-choke barrel?

        • B.B. Pelletier Says:

          Joe,

          You have asked a question that shooters have been asking for more than a century. No one knows for sure. Most shooters believe that a choked barrel is more accurate, but they give many different reasons.

          What I can tell you is that the great barrel maker, Harry Pope, always choked his barrels by about a half-thousandth. And the interesting thing is, many of them were muzzleloaders!

          There are intentional chokes and incidental chokes.

          Maybe I ought to write a blog about choked barrels and what people think they do?

          B.B.

          • David H Says:

            When you think about it, FX’s “Smooth-Twist” barrel takes the choking idea and adds one more element by adding the “rifling” at the end of the barrel too.

            David H

            • RifledDNA Says:

              When I was contemplating cutting a springer barrel down I researched about the chokes and found a few things- Springers and PCPs behave differently in regards to barrel length, spring guns use a fast burst of air and use all the pressure in approximately the first thirteen inches, I ended up cutting it at about fourteen inches where there was another tight spot but did lose the choke, the spot I cut at had a slight choke just smaller , its a good idea to find the tight spots. I have not lost any accuracy and since the gun actually broke in with the shorter barrel it is very accurate. PCPs need all the barrel length because the pressure is slow and continues to speed up the pellet all the way up. I went under but think its good ti get a full rotation in the rifling and since ags have a one in16″ twist, but experiments of cutting an inch at a time with a chrony is the best way to find the “sweet spot” and a good crown job after is essential. Hope this helps.

          • 103David Says:

            On the choked barrel, I’m a believer and I’ll tell you why.
            It seems that somewhere back in the eighties I ran across a colt python with a 3″ barrel on it and, having learned a 2″ is a great deal more difficult (but far from impossible) to hit with, and the aesthetic balance was far better than the box stock 2.5 inch item…well, soon it was mine.
            But there were a few oddities; notably, the serial number look-up seemed to indicate not only an 8″ barrel, but it was supposed to be in .38 special only caliber as opposed to the .357/.38 caliber that most Pythons have come in since time immemorial.
            Hmmm, mysterious.
            To make a longish story marginally shorter, and belatedly noticing there was no engraving on the barrel indicating caliber, Colt address, or anything, I realized my lovely 3″ Python was not only a cut-down 8″ barrel, but the cylinder had been reamed out for .357. And, of course the shortening of the barrel (VERY nicely done, by the way) had neatly removed the choked portion of the barrel.
            Oh well, I thought, It’s still a nice 3″ and I was far from convinced about the choke thing Colt flogged.
            Well, I had that barrel on the Python for a couple of years and it consistently shot…okay. But never great. It was a disappointment and finally I gave it one more chance and sent it off to Colt and replaced the cut-down 3″ with a new, choked 3″.
            The difference was not quite night & day, but close. All the sudden I could take a snub-nose .38 to the range and make money from the illiterate who really believed a snub-nosed .38 was only accurate at elevator-interior distances.
            That’s what the choke did for this particular revolver. Pope was right.

            But we still need the literary device of the epilogue.
            Somewhere not so long ago, I acquired a 6″ Smith K-frame. As lovely a piece of sculpture as we’ll ever see outside a museum…and achievable for we, the pre-millionaires.
            But here’s the funny thing, that 3″ choked barrel will still out-shoot the un-choked 6″. Not by much, but still, the difference is there, And it’s there every time.
            Go figure.

            • RifledDNA Says:

              I do have to point out that he was asking the risk of losing choke for an airgun, not a magnum pistol cartridge coming out of a 3″ barrel, uh big difference. I can understand how much difference that would make there, such high pressure and short length for the bullet to stabilize. I have found chopping barrels in .177 springers to decrease variations in poi between different pellets every time. I have to conclude the crown is far more important then a choke. Think of a slight variation in the crown of that magnum pistol, it will have far less of an impact on bullet flight then the same variation in crown on pellet flight. They are apples and oranges.

              • RifledDNA Says:

                Just goes to show though because he also was asking about pcp barrel shortening and I talked about springers! There is a huge difference there too. Springers tend to benefit more with barrel shortening then pcps do.

          • Matt61 Says:

            Sure, I was convinced by the choked barrels since the logic seems so sound and because the Benjamin Marauder is choked.

            I look forward to reading your article.

          • RidgeRunner Says:

            A blog on barrel choking would be a most interesting read!

            It is my understanding that the purpose of choking the barrel is to resize the pellets to a consistent size as they leave the muzzle. If you open a tin of pellets and measure each one, you will find they will vary in diameter, sometimes quite a bit. By choking the barrel you supposedly eliminate one of the many variables you have to contend with to achieve anal accuracy.

            I happen to have a 12″ .22 barrel for my TSS that was made from a Eun Jin barrel. I do not think that it is choked. When I get my TSS back up and running, I may have to try it out and see how it does unchoked and then choked.

            • Joe Says:

              I thought re-sizing a pellet via a choke in the barrel, distort the shape of the pellet, and if the distortion is not uniform, the pellet will not fly true. I assume this is less true of a bullet from a firearm because even a lead bullet is much less prone to distortion from a choke. Unlike a bullet, a pellet is NOT a solid core projectile and also it has a filmsy skirt.

              • RidgeRunner Says:

                Well, a LW barrel is choked and they are some of the most accurate air rifle barrels made, so there just might be something to it.

                • Joe Says:

                  Sorry,
                  Those Lothar Walther (LW) are not that accurate from my experience. The better ones are the old BSA, HW and Anschutz, and of the three the old BSA barrels (Daystate used to have in their old air rifles) are the most accurate.

      • RidgeRunner Says:

        It is my intention to remachine the breach end. I am wanting the benefit of the longer barrel, but do not want to lengthen the air rifle and want a little room for some baffling.

        • RifledDNA Says:

          My results of increased consistency with the 77 springers could also be from reducing the range of barrel vibrations with the shorter barrel and full harmonic dampeners. There’s a whole nother issue to think about.

          • Reb Says:

            I dreamt a prototype barrel choking tool up the other night- a pipe cutter with the cutting wheel replaced with another set of rollers and some plasti guage? Your thoughts?
            I feel this could be redemption for many an over zealous barrel lopper!

            • RifledDNA Says:

              I’ve heard of guys doing that but that it takes a LOT of pressure so it is better done with larger fixtures – they were saying some kinda lathe press I think.

              • Reb Says:

                Yes, a lathe would be ideal, however, how many of them used a lathe to lop it down, do you suppose?

                • RifledDNA Says:

                  That is very true. Better get a good quality pipe cutter, make that two so you can match the roller. How big do you think you would need? Going to need plenty of leverage and a good clamp on the barrel so its not torqued out of wack.

                  • RifledDNA Says:

                    Lord knows I’ve done that a couple times! Twisting tight brakes on and off.

                  • Reb Says:

                    We used an old school 6″ cutter for up to 3.5″. plenty of leverage there, and No, don’t try this with the barrel mounted in your gun! Unless you’re in desperate need of toothpicks!

            You guys need to slow down. I don’t know if you guys read any of the blogs and caught that I’m a machinist. Been doing it since 1982.

            I have cut a few barrels down and re crowned them over time. And have even straightened barrels. And I’m actually doing something similar like Ridge runner is doing but a little differently. I just took and machined the breech end of a .22 cal. Discovery barrel and I’m making some new barrel collars for that barrel diameter to put in my Talon SS.

            I’m making it for some longer range shooting. BB and a few people commented about different things using that barrel and different choices of what caliber to use. But I chose this barrel for a very simple reason. I already have it. And It’s just like another day at work for me and I actually enjoy doing this stuff. So I should be able to get back to finishing the collars in a few days. We been real busy at work so I ain’t had extra time to get anything done.

            And then about the choked or unchoked barrel thing I have heard alot of different things about that also. So to me that would be a excellent blog for BB to do. Matter of fact the sooner the better.

                And also maybe some new trick has been learned about a subject that was discussed in the past and wasn’t even thought about yet. So yep I’m always interested in new info about a old subject.

              I have no clue what you mean by we need to slow down… did we offend you? Anyway, I just did a test with my chopped .177 with ten shots from five different pellets,center to center was .30 at ten yards. So that ones good. When I figure out how to get pictures up this stuff will be on my site. Im eventually going to cut the new NP down but want to keep the shroud so I’ll need to retap threads for the new end. Getting used to the grip a little better but still finding a legacy stock, the only other on that will fit. Would love to whittle a nice maple one all custom like but boy would that be a lot of work. Be a heck of a reward though.

                Not offended at all. More like confused about what your were talking about with making a choked barrel. How was you going to do that?

                • Gunfun1 Says:

                  Or was you talking about cutting a barrels length shorter and then re crowning?

                  • RifledDNA Says:

                    Oh, well first it was about cutting barrels down then subsequently the benefits or negligibilities of chokes, then how could you add a choke to the chokeless chopped barrel, I had heard it suggested to modify a pipe cutter before elsewhere but don’t think it’d work very much, but that people do use some sort of press that incorporates with a lathe, I don’t have a lathe and that pellet test was just to show why I don’t worry about choke, at least not on springers.

              • Gunfun1 Says:

                RDNA
                Ok more clear now. Barrel cutting and re crowning on a lathe yes. Choking a barrel I would think that would be more difficult to do. I myself would like to know the correct way to do it. But I guess on the other hand I really never looked into choking a barrel because I have had good luck by just cutting and re crowning barrels.

                Go to the home page for the FX barrels and watch their video’s about how they make their smooth twist barrel. And if you watch their video of their factory tour it shows how each barrel they make is hand straightened by the owner of the company before its released for production. Also some cool tests they do on their guns also.

                  Back in the day, at least some barrels, were choked by what I consider step lapping, which actually removes metal from the barrel, requiring a larger projectile to fit the bore. I was just thinking of an easy way to choke one without removing any metal.

                    To me that sounds like it would defeat the purpose. That would be taking the material away from the lands of the rifling in the barrel.

                    • Reb Says:

                      That’s the art of it! they worked from the breech end so this was the larger part of the bore, from constant abrasion while the muzzle end was only minimally worked, therefore having the smaller diameter,or choke.

                    Reb
                    Sounds like more trouble than its worth.

                      Think about how much more accurate any barrel would be with a finely tuned choke.

                    • Reb Says:

                      This is the reason for the tool, and, if it worked and was done correctly would allow you to “fine tune” your choke.

                    Thats the qestion Joe asked.

                    I dont know if a choked barrel would or wouldnt be better.

                    One way would be to try is the best I can say.

                  • Wulfraed Says:

                    I was just thinking of an easy way to choke one without removing any metal.

                    Probably requires annealing the barrel to make the metal “soft” enough to flow under pressure, then cranking a tapered set of rollers around the muzzle end (that referenced pipe-cutter, with the cutting blade replaced with a flat wheel), followed by heat-treating the barrel back to original hardness.

                    • Reb Says:

                      Genius! I don’t know if annealing would be required, but Yes, you understand the concept.
                      Thanks, I thought i’d gone rogue!

                • RifledDNA Says:

                  Yeah, I think the chokes don’t really make much sense, I mean they sound good in theory, size the pellet, but the pellet was already sized with the skirt blowing out and engaging right from the get go. It seems realistically like it just increases friction, maybe in pcps will help give a last ditch pressure boost, but springers have already lost all their pressure. I think chokes have their place but its on shotguns mostly.

                  • Reb Says:

                    I think you just hit the nail on the head!
                    in a high power springer the blast of air is so intense that the skirt is forced into the rifling, creating a leak free seal, for more power and accuracy, however with other power plants, the blast of air is much slower and with less heat, making it inadequate for creating such a seal. I hereby postulate that these other power plants will benefit far more from a choke.
                    Or I could be wrong. ;)

                  I forgot to say Ive been meaning to check out the fx smooth twist, I wonder why no one makes the micro groove barrels like the Marlin .22s? Think that would work mint for pellets. Maybe too much friction but they look cool.

                      My 953′s rifling is reminiscent of this,I’ve never counted the grooves but you can tell it is high quality. I saw a buncha used ones the other day, from a shooting club for $50-$75. There’s no telling how much work went into those guns!

    Again, great article. I like to know why some PCP airguns such as the HW100 don’t allow a user to adjust the gun’s pellet velocity?

    • kevin Says:

      Joe,

      I’m not B.B. and I don’t play him on TV but………

      You can adjust the velocity on a HW100. I fiddled with mine. The fac versions are easier to adjust than the 12fpe versions.

      You should adjust both the reg and the hammer spring preload when adjusting the power on a HW100. This keeps everything in balance.

      Here’s a decent video on adjusting the HW100.

      http://www.youtube.com/watch?v=OEb7Oeif-C4

      Here’s a good analysis on the workings of a HW100:

      • Joe Says:

        Thanks, but let me re-phrase my question, and this is what I intented to ask: Why can’t we externally and easily adjust some PCP airguns, like the HW100?

        • kevin Says:

          Joe,

          I think one of the reasons is cost. I think another reason is because the majority of airgunners adjust the power for their needs and leave it there even if it has an external power adjuster. I have pcp’s with external power adjustments and rarely use them. Verifying trajectory at one power with one pellet is enough for me. Too many variables and the gun becomes ineffective for me.

          Seems like most of the airgunners I know and shoot with treat their variable power scopes the same way for similar reasons. They set their scope on one power and leave it there.

          Just my opinion.

              We may never get a straight forward answer and if you did get a answer from Weihrauch for example it would be one that you didn’t want to hear. So lets just say that it would add extra cost to the end of a rifle then what if the gurus out there say that the adjustment looks hideous and criticise and comment how it would work better if they did x.y,z like some other company did on their guns. PCP is one of the first design in air gun history but yet the modern versions are very new to air gun world so who knows it may be a standard in the near future. I don’t like were we are going with air gun prices good 177 ammo is close to 22lr ammo we are going backward where only the wealthy can afford these 1700-1800 kinda like when cars came on the scene only the rich had them, but now who can afford a horse, not me.

            • B.B. Pelletier Says:

              Joe,

              Here is what I believe. Weihrauch is not a company of airgunners. They were 40 years ago, but those days are past. They still make great spring rifles, but I don’t see any innovation coming from them anymore.

              They built the HW 100 is a conservative, conventional way.It is a fine air rifle, butt it’s not in tune with what is happening in 2014.

              I would liken Weihrauch to the Checker corporation. They continued to make a fine 1958 automobile well into the 1980s, even long after the market had moved on.

              That is just my opinion.

              B.B.

              • Joe Says:

                B.B.,
                I was hoping that your answer is that companies like HW doesn’t want users to easily adjust the velocity because it would lead to a less consistent velocity, or looses accuracy, or waste of air, or maybe even damages an airgun. I do however agreed with you that HW is conservative in their airgun design, but HW was never a very innovative company to begin with even 40 years ago. After saying all that, HW does have one air rifle that I thought is innovative, and that is the HW57. How come PyramdyAir doesn’t have the HW57 in stock?

                • B.B. Pelletier Says:

                  Joe,

                  I’m going to disagree with you. HW is the company that invented the Rekord trigger — the most copied airgun trigger ever.

                  HW created the HW77, the most copied underlever design.

                  HW created the HW 55, the recoiling spring rifle that won a gold medal in 1969, shooting against recoilless target rifles.

                  HW created the HW 52, a target .22 rimfire that at one time was the best in the world.

                  HW was a very innovative company, in my opinion. You can’t just judge them by the last 20 years. Ypu have to look at the entire 20th century.

    Hey BB,
    I know you’ve talked a lot (a lot!) about trigger mechanisms before, but i don’t remember you going into depth in a single (series of?) article(s) explaining the intention and movement of each piece and how they work together. If you have, would you point me to them. If you haven’t, would you mind writing about this. I can see how much of it works, but then I get confused by the ups and downs and pulls and pushes and springs of the whole thing working in concert. Or maybe there is great variation between models where explanation is difficult and doesn’t carry over between brands? Again, if you’ve already done this, then I’d be glad just to read those articles if you could direct me to them.

    Thanks for your hard and revealing work.

Also I’d like to say this is my first comment on the blog despite having been reading it voraciously since around 2006 or so whenever the airgun bug bites me. I have to give my deepest gratitude to Mr. Gaylord first and foremost and everyone else who contributes all the information that makes this one of the greatest airgun resources on the internet that I know of. More often than not anytime I have had a question or an idea pop up, someone with much more knowledge than me has likely tried the idea and/or the airgun in question and posted their results here. This blog here has saved me countless hours of futile experiments and alot of money in the process and has allowed me to refine my tastes down to the pure essentials of marksmanship which is the foundation my hobby is built upon. Especially these days with the burgeoning growth of the hobby it can be all too easy to get lost in the swarm of marketing fluff and over-hyped velocity numbers, and I truly thank you all for sharing your experiences on here day in and day out.

I used to own a RWS M34, and a M54 Air King that I miss tremendously. I sitck to .177 unless I hit the lottery and get into PCPs. I’m currently saving up to finally add a FWB 300S that I’ve lusted after for 10+ years, and hoping to attend the Flag City Toys That Shoot show in April since I’m only 2 hours away.

  • Awny Says:

    BB.,

    Unfortunately Talon SS does not put an end to top hat adjustment. When I bought Talon SS last year the power wheel was the main advantage that made me choose it over the Marauder. However to my disappointment the PW gave almost no control on the pellet speed. Barely a difference of 20 fps between level 0 and level 10. Nearly a constant speed independent of the setting. Nothing close to the 400-800 fps range AF claim. I called AF and PA and the only answer I got was that each gun is different. I then learnt about the O-ring trick. It did the job and I was able to control speed down to 400 fps or less even. By the way, where do you get a good selection of o-ring for such jab. I got mine from home depot which, despite doing the trick, are a bit lose for the placement and I wish I can find tighter one that would give more consistent positioning of the ring during shooting.

              Bit more S55 info for you…
              In spite of a lack of good outdoor weather for shooting , I have found that I should treat it like I would treat my other PCP guns…
              When shooting on the higher power settings, it needs to be shot once to settle the valve and prevent a weak first shot.
              When leaving it sit for 3 days (let’s just call it “overnight”) it will need to be shot once for the same reason.

                TT
                You are right again. If I shoot my PCP guns after they sit over night or longer my first shot will always go low.

                No matter how bad I want to make a shot out of the back door at a pest. I dry fire the gun before I load a pellet and open the door to make the shot.

                • twotalon Says:

                  GF1

                  I always shoot a pellet to make sure the power plant sees the right conditions. If a “blank” works for you, then you can save a tin of pellets over time.

                Could this be exhaust valve extrusion?

                • twotalon Says:

                  Reb…

                  Maybe in the case of letting it sit too long without shooting, but the part about needing to shoot after a fill is probably due to a change of conditions caused by a different pressure and a need to self settle at the new pressure to get back into the curve right.
                  The valve bounces then settles depending on pressure and back pressure from every shot . Normally there is a gradual change as you shoot off the fill, but things get out of wack when a sudden change happens. If you only adjust the power setting on a Talon, the next shot will not come up right. Needs to waste a shot to get on the new curve.
                  Common PCP problems. Get to know the individual gun and live by it’s rules.

                      Yeah, adjusting scopes can be a bit funny too. They can be O.K. if you get them figured out and they can work well, but if you try to adjust them the way most people THINK they should work, then they will cause you nothing but trouble . On top of that , a lot of people will not even recognize that the source of their problem is the scope. Lots of hair pulling and maybe a lot of time and expense wasted on the rifle, or maybe selling a perfectly good rifle.

                And sorry but I would rather be shooting out in that not so good weather over watching a movie. Come on TT you know you want to go out and shoot.

                Heck look at me sitting here on this computer talking right now. It’s supposed to be around 60 today but rain is in the forecast. So I’m getting ready to go out and do some shooting here in a minute. It will be Monday before I know it and then back to good old work again.

                  In my younger days I would have been out shooting, but it is cold, windy and snowing at the moment. I am not going to get any good data in that. And I don’t feel like trying to dry off a gun afterwards.
                  Maybe a day next week I hope.

    Off topic; Has anyone built a speargun from the tubing used in the expanding water hoses yet?

  • Reb Says:

    It says my username is already taken, which I highly doubt. Maybe I’ll try another later.

    • RifledDNA Says:

      WordPress is kind of a pain, there’s .com and .org which apparently are completely separate. I guess the .org profiles which are the basic ones for just posting on here and then the .com I had to do a whole new registration to make the blog site. I don’t know if it requires a .com profile to use the .com blogs but might be.

    • RifledDNA Says:

      Making a .com profile is how you get the cool little profile avatar and its then attached to your email address and will show up anywhere you web post with any account with that email… cool!

        I’ve got an idea for an Avatar but it will take some doing to set up. Can I change usernames later? Or would that still not work?

      I just remembered something when I seen your reply. How is that hop up going on that 760 barrel. Any luck?

        • Gunfun1 Says:

          Reb
          I will let /Dave explain if he see’s my response. It got started when we were talking about airsoft guns. It was his idea. And he has been doing the experiment so he will be able to answer better than me.

      • /Dave Says:

        Gf1,

        I haven’t really gotten any good results to post yet. I tried different amounts of protrusion into the barrel but all that happened was it spread out the groups even farther than without. I didn’t get the barrel drilled and tapped closer to the receiver yet. If you recall, I had the hop-up set close to the muzzle for this round and eventually will try it close to the receiver when I get some time.

        /Dave

        • Gunfun1 Says:

          /Dave
          Yep I remembered that was the results you had. And that your were going to try it by the receiver. That is what I was thinking about if you got to test it after you drilled by the receiver.

          Maybe that will work out better that way. Might give the bb more time to stabilize I’m guessing before it leaves the barrel. Well like I said still interested in the outcome of the experiment. So post when you get some info if you will please.

          • /Dave Says:

            Will do! I’m still dinking with the LG55 too. I changed grease in it and that didn’t help with the velocity so my next stop is to play with the piston seal some more. It’s a bit tight. I could wait for it to break in after a thousand or so shots, but since I also play with my other toys that might take a while….

            /Dave

            • Gunfun1 Says:

              /Dave
              I forgot about your LG55. Your going to try a different lube?

              And I knoow what you mean about the other toys. The old R/C airplane bug is starting kick in again. I use to fly in the winter all the time. But the old fingers dont work as good in the cold anymore.

            • klentz Says:

              /Dave,

              Setting velocity aside for a moment…how’s the accuracy in your LG55? What pellet has proven most accurate? Thanks.

              Kevin

              • /Dave Says:

                Accuracy is nice, Kevin! H&N Finale Match Pistol seem to do the trick for now. Meisters are next. If after the next round of fitting it’s still misbehaving, I might want to come see you about the original factory spring (if you still have one). That might be a little stronger than this JM spring. I don’t really mind the lower velocity, but it’s giving too wide of an extreme spread even with the new seal. Enough to where you can hear it and see the vertical poi’s change..

    • Edith Gaylord Says:

      TT,

      I don’t ask him to mow the lawn. He insists on doing it. I’ve offered to have a service do it for him, but he says that doing chores is a good way to remain active and independent in his senior years. He’s right, and I’m of the same opinion.

      We have a relative who just wants to sit and wait for old age to force him to move to an assisted living facility. Nuts to that!

        You keep going as long as you can. Particularly if you feel up to it. Otherwise you are just giving up. Some people would gladly take away your last good years if they could. Maybe the shoe will be on the other foot some day. See how they like it then.

  • Reb Says:

    O.K.,I finally got a second shot outta the 392! After 25 pumps I stuck a .22CPHPthrough an aluminun tag an 1/4″ deep in an old telephone pole, the second shot was a Gamo .22 round ball, again 1/4″ deep. Wow! I actually feel slight recoil from this gun @ 8 pumps.
    I don’t expect I’ll be using this knowledge very often, but it’s nice to know I have the option. ;)

    • twotalon Says:

      Reb

      You are going to beat your gun to death doing that. That’s a lot of wear and strain. Take it easy if you want it to last for a long time.

      twotalon

      • Reb Says:

        That’s what I meant! It will do it but not for long. at least not without some parts from Mac1. I was prepared with another pump cup, or for valve lock, just in case, and now I know the intricacies of going that far with one.
        I can’t wait to get the 3120 going again! It’s just a much more solid gun, That’s why they require less modification.

        • twotalon Says:

          Reb…

          Have fun with it. People have turned pumpers into short shot count PCPs. Decide if you think it’s worth it.
          I am not much into mods, unless there is a particular need to do so. I tend to try cleaning up original glitches if I can without much trouble and then live happily ever after. Just about every gun I have gotten hold of had at least one sore spot that needed cleaning up.

          • Reb Says:

            I just like the idea of having a follow up shot. Them squirrels is tough!

          • Reb Says:

            The only mod i’m considering for the 3120 is a debouncer, and only if it needs it.
            I’ll probably see what the valve looks like next month and go from there.

  • RidgeRunner Says:

    Way up yonder y’all talked about how in a sproinger it was not necessary to choke because the skirt flared out. My CFX would shoot dime size groups with 4.52mm FTTs, but quarter size with 4.51mm. It may not be a good idea to choke a sproinger because of the low volume of air, but with a PCP you have more air.

    • Reb Says:

      I spit out a buncha stuff right around there. I can’t remember it all. I’m glad it’s gonna be in the archives though!
      I think I ran Two Talon off with some of it, for which I offer my apologies.

          That’s another thing.
          I find it difficult to focus with alcohol in my system.Since I’ve started shooting on a daily basis, I no longer drink if I want to shoot. I have gone from a 6 pack a day to one maybe 2 beers a night, saving myself about $5 per week! This money goes toward my shooting budget and coupled with all that pumping I’m in much better shape than a year ago.
          Once again, I would like to express my gratitude to everyone here.Thank You!

    • Reb Says:

      Yes IMO they may create excessive friction depending on placement in a springer.
      Go to the post where I started with “I think you just hit the nail on the head”.

    • Reb Says:

      4.51 is apparently too small for your bore. Have you tried a 4.53 or is it even available?

      • RidgeRunner Says:

        It is not the skirt diameter, but the head diameter. As to whether they offer 4.53, I do not know. If you go through a tin of pellets, you may be surprised how much variation there is. When you get into the “match” pellets, supposedly the manufacturer has sorted through them by size and weight and they are more uniform. That is where you start seeing the 4.50, 4.51, etc. on a label on the tins.

    • Wulfraed Says:

      Which may demonstrate where a choked muzzle comes into play …

      Centering the head of the pellet so it is not tilted as it leaves the muzzle.

  • Reb Says:

    Wow! I feel like my brain is gonna explode!
    Most excellent blog,Gentlemen OOps and Ladies!

  • Reb Says:

    B.B., Does anyone offer a Mini Ball style pellet?

    • RidgeRunner Says:

      H & N does, in both .177 and .22.

      http://www.pyramydair.com/s/p/H_N_Rabbit_Magnum_II_177_Cal_15_74_Grains_Cylindrical_with_Round_Nose_Solid_200ct/754

      Be advised. Read the reviews before you order any. No one, including myself, recommends them. they are a waste of good lead. I have some in .177. They will not even load in most barrels. One guy tried them in a Condor and they were horrible, so power is not the answer for these things.

      Try the H&N Baracudas. If you need more power than they give, you need more air rifle.

      Just remember this basic rule: What good is 500+FPE if you can’t hit what you are shooting at?

      • nowhere Says:

        The fact that I’ve never heard of anyone getting anything better than terrible results with those things always surprised me. In all my airguns so far H&N pellets have worked as good or better than the other brands I’ve tried (JSB, RWS, Crosman Premier). Even their non-lead pellets turn in accuracy in my HW-77 and FWB 602 not too far off what I get with the Finale Match! And yet there they are, the Rabbit Magnums which can be put through a rifle which is a normally a tackdriver and have trouble hitting anything smaller than a garage door! It’s baffling. Are all the sales to shooters who buy them once to try them out?

        • RidgeRunner Says:

          Very likely. I keep pulling them out when I pick up a different air rifle, but the results are always the same, ugh.

      • Reb Says:

        a Mini Ball has a recess in it’s base, much like a pellet. I don’t think the rabbit magnum has one.

        • RidgeRunner Says:

          Actually, it does have one with a thin skirt. It just does not shoot worth doodly out of anything I have tried.

          • Reb Says:

            I won’t be buying any and never have considered them for purchase. They are too heavy for anything I have, and I remember my black powder results with conical bullets.
            However, I am luvvin’ the round balls in airguns!

      • Reb Says:

        They probably require a much faster twist rate to stabilize due to their length, size and shape.

    • B.B. Pelletier Says:

      Reb,

      I have never heard of one. There isn’t enough explosive force in an airgun to0 obturate the skirt. Diabolo pellets are the closet thing airguns have to real Minie balls.

      B.B.

  • Reb Says:

    Somehow I see this choking blog as a history lesson on the civil war era and advancements in technology that came from it.

  • Reb Says:

    It sounds like H&N should swage all those rabbit magnums to include a hollow base. It couldn’t hurtany more than marketing a bullet for an airgun. I have had very good results from all H&N pellets I’ve ever used, even the rebranded ones, which are the best deals I’ve run across.

    • RidgeRunner Says:

      As I just posted a little higher up a few minutes ago, it does have a hollow base with a thin skirt. It does not seem to help any though.

  • Oliver Says:

    B.B.,

    I am a UK resident and have been following the blog for some time now and it is truly fantastic. Apologies for changing the subject but I really wonder when Umarex will release some more pellet pistol replicas. Might you know why they seem so hesitant to release new ones this year? Is it the R&D involved which makes it prohibitively expensive when compared to BB action shooters. I have scouted a great number of blogs, particularly in the UK and there seems to be a far greater demand for new pellet pistols than for BB replicas so can’t see why Umarex is disinclined to release new models for 2014. Would you be able to shed any light on this?

    Regards,

    Oli

    • B.B. Pelletier Says:

      Oliver,

      They aren’t being reluctant. I am reporting on the Colt Python revolver starting tomorrow.

      What you are experiencing is the time distortion that results from my reporting on a trade show on the internet. You find out months before these guns arrive for sale. It has always been this way, but reporters were not able to get the word out as fast when there were only magazines in which to report.

      Umarex is pushing replica airguns just as fast as they can.

      B.B.

  • Gunfun1 Says:

    I will have to say after I did the o-ring behind the top hat trick. That I did have to re-adjust my power wheel and fill pressure of the gun. I was able to go to a lower fill pressure.
    I just wish I knew why. :)

  • Reb Says:

    B.B., I’m between jobs right now and have considered this for some time.
    How do you suppose one would go about getting into airgun manufacture?
    I would be interested in just about any aspect I can think of.
    Is there anyone that may need help out there?

    • B.B. Pelletier Says:

      Reb,

      I’m going to do you a big favor now and tell you that asking the question like that means that this is something you definitely DO NOT want to do.

      You do it only when you cannot stop yourself from doing it and it takes over your life. Ask Lloyd.

  • Reb Says:

    RDNA, I just found an OK. Nova for sale, that looks just like the gun you picked up the other day, same lever and all.

  • Reb Says:

    OK, here we go! I’m assuming that co2 can be used in a hpa tank however not the other way around?
    I’m also considering a vortex block for the feeding mechanism, running .22 round balls or possibly a forced feed like the Crosman 2100. Any thoughts? If anyone has any ideas concerning the valve work, just spit ‘em out, I’m all ears!
    Thanks for your considerations!
