Air Venturi Bronco with optional target sights: Part 4

by B.B. Pelletier

Part 1
Part 2
Part 3

You know how your wife buys a new trash can for the kitchen, and it doesn’t match the front of the old refrigerator that you’ve been talking about replacing for several years? So, you buy a new fridge, but you want this one to have an ice dispenser in the door; so, you hire a plumber to run the water lines; as long as he’s there, you decide it’s time to replace the chipped sink with a new stainless-steel double sink; but as long as he’s under there, you might as well have him replace the water supply lines and the waste pipes. Then, your wife doesn’t like how the new sink looks against the old green Formica counters, and she wants those granite countertops you’ve been promising her ever since you forgot your 17th anniversary; but the new countertops won’t look right on the old painted cabinets, so you decide on some Scandinavian teak cabinets with glass doors; and now the chipped dishes look out of place. [Note from Edith: This is hypothetical. It’s not a true story about us!]

So, seven months later, the total bill for the new trash can comes to 70 thousand dollars? Well, that’s what I seem to have gotten into with the Air Venturi Bronco. I was just testing the new Bronco Target Sight kit on the rifle, and I raked back the compost pile a little too far. So, today, you’re going to benefit from my puttering gone amuck.

I took a lot of heat from you guys in my last report. You didn’t like how I did things, plus I introduced the new Air Venturi Pellet Pen and PellSet and called it maccaroni without any warning! Well, shame on me!

I began today’s test by mounting the Hawke 4.5-14x42AO Sidewinder Tactical scope on the rifle. The Bronco has a hole for a vertical scope stop pin, so I was able to anchor the two-piece mounts rock-solid.

I thought I would back up just a bit and see just what the best pellet is for this rifle, and then see if there’s a difference between seating that pellet flush and seating it deep. I started at 10 meters with five-shot groups, just to weed out the pellets that were not worth pursuing. They were all pretty good, but the lightweight Air Arms Falcon was just a bit better than the rest.

I realize that this is a test of a peep sight, but my last report raised some questions about the rifle’s accuracy that I felt needed to be laid to rest before the test was continued. I’m validating the rifle before I continue reporting on the new sight.

Then, I backed up to 25 yards and shot two 10-shot groups. One was with the pellets seated flush with the end of the breech, and the other was with the pellets seated deeper, using the PellSet. Let’s look at my results before I analyze them.


Ten Air Arms Falcon pellets seated flush with the end of the barrel went into this 25-yard group that measures 0.531 inches. The group is reasonably round.


Ten Air Arms Falcon pellets seated deep with a PellSet made this 0.821-inch group at 25 yards. Nine of the ten pellets went into a group measuring 0.564 inches.

Conclusions?
Looking at both the shape and size of these groups, I would be tempted to say the flush-seated pellets shot best. And there’s no doubt that this Bronco can shoot. But let’s not make up our minds just yet.

See that “flyer” in the deep-seated pellet group? It wasn’t a called flier. The hold and release were perfect. There is no reason that pellet should be that far away from the rest of the pellets at 25 yards.

What I’m not showing you are some other 10-meter groups with different pellets that also had strange fliers like this one. I had removed both the front and rear sights, so we can’t blame the front sight screws for being too long. But something is happening with this rifle that’s unusual.

Edith questioned me in the same way that I know the rest of you are going to question me. Didn’t I have good groups in the past? Why is this rifle suddenly shooting like this?

I went back and looked at the groups I shot in Part 3 of this report. If you do the same, you’ll see a couple “fliers” in those groups, as well. The difference is that those groups were shot at 10 meters instead of 25 yards.

So, then I went back to the 7-part report I did on the Bronco and examined those targets. In Part 5 of that report, I shot the rifle with a scope at 25 yards and guess what? There are “fliers” within some of the groups.

What’s happening?
I think the Bronco I’ve been testing is extremely accurate, but it has also been throwing fliers like this all along. I chalked them up to my poor shooting instead of something else. Now that I’ve examine the rifle under the microscope, I’m not so sure it was me. I think this rifle has been tipping pellets all along. It’s only when the gun is fired at 25 yards that this becomes evident.

I think this has gotten worse recently, but I cannot say with certainty what’s causing it. It’s clear from the two groups shown here that the rifle can really shoot, but I think it can do even better than it currently is.

I have a plan to try to remedy this situation; and, at the worst, it will not affect the accuracy of the rifle. But if I succeed, this rifle could shoot smaller groups than you see here.

I need to try my remedy before returning to finish the report on the peep sight kit, because I think it has been affecting the results. And there’s a second problem I’ve identified with the peep sights that has nothing to do with the sights, themselves, but with how I’ve been sighting the gun. I’ll describe that problem in detail for you and tell you how to easily avoid it.

Til then!

  1. Until then… Until then, what??? You can’t just leave us hanging like that! That’s just mean!
    I think it’s one of the biggest cliffhanger since the change from blogger to wordpress!
    I just can’t wait for it.

    I don’t have 25 yards to test my own Bronco, could your remedy change things at closer range too?

    You really are a great writer, I wasn’t there in the airgun letter days but I hope you didn’t end reports like that to have the guys waiting so long for the other part, a few days is OK (because you DO plan on having the next part out this week right?) but a few weeks… I’m not sure I could have waited this long.

    • J-F,

      First of all, my rifle may be special. When I show the problem (if I’m right and there really is one) you will see how minuscule it is and why other rifles probably don’t have it. So just keep shooting your rifle and enjoying it’s accuracy and let me get to the task. Until then, we won’t know whether what I suspect is real or not.

      Secondly, if the accuracy is improved, it will hold at all distances. It’s just a lot more difficult to detect at closer ranges.

      • Utkarsh,

        Wow! You don’t give a guy much of a chance, do you? You buried your comment deep within the comments section, where it took some doing to find it!

        I thought a screw from the open sight was tipping the pellet as it passed by. I didn’t write a report about that because I couldn’t prove it.

        There was never a Part 5 to this report.

        B.B.

  2. BB,
    A couple of reports ago, I got curious about the original Bronco groups and went back to check. I noticed you didn’t give any group sizes that I could see and they weren’t much better than the later ones all things considered. That always puts my antennae up, so I’m glad you are revisiting the situation, as I think something was amiss, given the “field reports” on Bronco accuracy.

    • BB,
      One of the reasons I like your tests is that you don’t usually pull any punches or give any consideration unless noted (as in when you tried to make the TF87? shoot well). I always enjoy the trip, even when it is like vacations in the old days, where you never knew what kind of food the only available restaurant might have or if you could get the key to the restroom first before the brothers! You knew that the trip was your loving parents’ idea of a good time and good for you, even if they might not have known exactly how to make it a flawless excursion with perfect food and accommodations. I hope that makes sense :).

  3. For my part, I can only speak to the size of 10 yard groups with my Bronco. When I make the leap to 25 yards, I have too many other rifles that are better suited to that range. I will say that at shorter ranges, say 10 to 15 yards the Bronco is hard to beat.

      • I finished (finally) my 10m scoped practice, after several hundred shots. The goal was to get everything else out of the way before tackling the peep sight, so I was carefully watching each shot. No more than four in each group, but the target had 12 bulls and that allowed me to see exactly how accurate each shot was. I did not see any unexplained fliers.

        Returning now to the peep sight, I’m seeing a nice improvement. I’ll wait for your future comments on using that peep sight to see how they correspond with my experiences in learning how to use it best. Or, a little better. I’m still working on that one.

        It’s tempting to try your 25 yds but I’d need to do it outside and even a little wind can make it difficult to get reliable results at that level. Hitting 40mph gusts here today.

  4. You had better fix it. In a few years my grandson is likely going to want an air rifle of his own and I am going to want to get him something that is interesting.

  5. I shot my Bronco extensively a couple weekends ago. My preferred range is a measured 50 feet. I was flush seating the pellets (CPL’s in the box) and getting similar results; nice tight groups with the occasional flier, bench rested. The fliers I always blame on my technique or an aberration in the pellet. I was using a Hawke 3-9X cranked all the way to 9X. Weather was perfect with light variable wind.

    B.B., I do have a question though about that scope stop hole that you mentioned. I thought I read in the manual (I could be wrong) that that hole was for oiling the compression chamber?

    All in all, it is a great rifle, and at that price point, definitely a must have.

    Also….I think I’m going to order an Edge in a couple weeks from PA. That rifle has always been calling my name and I think I’m finally going for it. Also going to get the Beeman P3 or Beeman P3 Gold. Any particular differences in these two pistols, other than the “gold”? The gold model looks like it has fiber optic sights whereas the regular P3 has regular iron sights. Particularly, is the trigger pull any different?

  6. BB: I like the analogy you used to start to days blog because I remodel houses for a living and that’s often how projects get started and morph into bigger ones. At my house though nothing like that would happen because I’m to burned out on home improvements that almost nothing ever gets changed. As to the Bronco,I used the hole in the top of the receiver as a scope stop also, and I also wondered if it was originally meant for oiling like on the other Mendozza made springers. On the fliers, I think that something is maybe nicking the base of your pellets. When I shoot RF and I get fliers for no reason, I suspect the ammo, and nicked bullet bases (which you cannot see with loaded RF ammo) is often why. As an aside ,I think I just convinced my neighbor to buy a Bronco after he shot the one my son has. We also shot my Diana 24 which he also liked.To illustrate how much fun it was NOT to shoot a untuned magnum springer and why technique to shoot a powerful springer is not an easily acquired skill, I had him try my 177 Bakial MP513.

    • Robert,

      Thanks for what you said about impromptu remodeling. Edith thought I was kidding!

      I agree on the nicking of the bases of my pellets. I even think I can see the evidence, but until I can examine things closer I won’t know for sure.

      B.B.

      • BB: Another senario in impromtu remodeling,is another type of customer I sometimes encounter who also wants things done “while your at it” Like when they want a new patio door and wall switch has to be moved and the sills are rotten . Only thing is, they think that part is free. We call those folks “grinders” in my trade.

        • BB’s story reminds me of the day my wife sent me to Lowe’s for a “Garden Claw” and I came home with a new Troy Built tiller. Not the cheapest one, either.

          I’m an easy sell.

          Les

      • I let out a great big gafaw when I read BB’s description of the cascading kitchen in this Bronco post. For the past two months I’ve been remodeling my kitchen – for the past two months I have had no kitchen. No sink, no cabinets, no floor, no base boards, bare plaster walls. What I have is a dishwasher (so grateful for that) sitting in the middle of rubble and a coffee maker on the bathroom sink. I’m exhausted and sore – doing all the work myself, and, worse than that, I’m behind on this blog. Why? Because all I wanted was a new counter top. You know the rest of the story.

  7. BB,
    This report and the last one on the Bronco reminds me that what you have is a JOB! I was thinking about it the other day. When I shoot it is for fun. When you shoot, a companies sales are at stake, and every group is used to judge the quality of the rifle or pistol. I think for the most part, you enjoy your work, but it isn’t as it sounds.

    I appreciate the honesty you give us with every report. I enjoy reading the blog and appreciate all the work that goes into it.

  8. I don’t usually brag, but just this once since we’re talking about group sizes and such. I’m 2.5 months past surgery and have pretty well recovered short term strength if not long term endurance, so I’m trying hard to get to the basement to shoot on a regular (3-4x per week) basis. I know much of that recovery will be lost again once the radiation treatment starts, so I’ll make the most of what I have and hope for the best.

    Yesterday evening’s shooting was gratifying: I put 8 pellets in a group the size of a dime from 10 meters. Blew out the center of the hole, which was almost exactly at the 10X ring so I can’t score it. You say that’s nothing special? This was done with my LP-10 pistol! In the proper one-handed stance.

    Now, if I could do that on every target…

  9. Howdy Mr. B.B., Ms. Edith & The Gang, B.B.’s attention to detail + ability to translate it into words & the gang’s input all add up to an incredible talent/knowledge pool for a wannabe like me. Thanx.
    Beaz

  10. This is quite the masterpiece of detective work. I can’t imagine what the solution will be.

    The whole remodeling business reminds me of a scene from the Brad Pitt film Mr. and Mrs. Smith about two spies married to each other under the cover of a suburban couple without knowing each others’ identity.

    Angeline Jolie: How do you like the new drapes?
    Brad Pitt: I don’t
    AJ: We’ve had this conversation.
    BP: Yes, we said we’d discuss it.
    AJ: You’ll get used to them.

    Conducted a bit of research into shooting history the other night. I understand that at a famous match in the 19th century between the Irish world champions and an American team at Creedmoor, NY, it all came down to a final shot (1000 yards) by an American. Both sides had matched each other with perfect bulls until one Irishman shot the wrong target! Everything was riding on the American to make his final shot. So, what does he do, but ask for a ginger beer to steady his nerves!? Then the darn thing pops under pressure while opening and shatters, sending slivers of glass into his hand. But after this goofball move, he ties up his wounds with a handkerchief and proceeds to make the winning shot. I happened to come across ginger beer in the store the other day and thought I would give it a try to see just what the siren’s song was for this shooter. It was all right and somewhat different but neither terrible nor especially memorable. It seems to be one of those fads that came and went unlike Coca-cola which dates from the same period I believe but has touched some kind of deep nerve in the human psyche.

    B.B. and Mike, that’s encouraging news about my No.4. I understand that the products of the Long Branch Arsenal (like mine) were supposed to be particularly good. But I’m not in a hurry to find out as I’m enjoying the dry firing with great accuracy. One thing that surprises me though is that the ejection pattern of my snap caps is all over the place. In part that is due to my frenzied working of the bolt during rapid fire but not entirely. On the other hand, the Mosin sniper rifle ejects with such precision that I can almost practice marksmanship while ejecting the rounds. This is not what I would expect since I understand that the British sweated furiously over every last detail of the Lee-Enfield design through its long history, and my 1950 Long Branch should be just about the summit of production. On the other hand, the Mosin is routinely laughed at for the roughness of its construction. Not sure what this ejection behavior says about the design or construction of the two guns. It would have to do with extractor design presumably.

  11. I avoid ginger beer while shooting, although I do like to take along a canteen of water. When I’m not drinking from it, it makes a nice rest for my hand.

    Just got back from the range. Tried out the .22 barrel on the RS-2. Shooting CP .22 hollowpoints, 25 yd.
    6″ Shoot-N-C targets. 75 degrees, partly cloudy. Wind NW 20 mph.

    RS-2 equipped with Tasco 3-9x50mm. scope. Sitting at bench.
    The gun started shooting way low, because the scope was adjusted for use on the .177 barrel. After I got it adjusted for elevation, it shot 275/300. A second target shot 274/300.

    This isn’t the best I’ve shot with any air gun, but it was the best this particular gun has shot. At least it is consistent. I think it would have done better on a calm day.

    Imagine how that poor Irishman must have felt after shooting the wrong target! The American was lucky the exploding pop bottle did not get glass in his eyes. Talk about breaking your concentration!

    Les

  12. I like your opening story. It reminds me of one I heard about “First Year’s Cost of Burning Firewood”. It is along the same line ending with purchase of a $40K Truck to haul wood and a trip to the ER when you drop a tree on your foot!

    Mike

    • What… ER for just a flattened foot?

      What about the chainsaw gash nicking the femoral artery!

      Change of subject — shooting Raccoons is hard… Especially when the camera lens has trouble focusing in the dark at f6.3. <G>

      Not to mention that it is skittish, and sliding the patio door open tends to spook it.

      Apparently dried cobs of feed corn don’t interest ‘coons; it turned its nose up at the cob I tossed out in favor of loose kernels and sunflower seeds that it collected using the “look at the sky while pawing the dirt” technique.

  13. Please offer this rifle in .22 ! Lobbing the bigger pellets at low velocity is a hoot, and the bigger pellets are easier for us ham-fisted or arthritic-fingered guys to load.

  14. Greetings, B.B. Hope all is well with you. I have been reading up on the Air Venturi Bronco, and the Stoeger X5. I am thinking of trying a spring piston rifle and have been reading up on the Air Venturi Bronco, and the Stoeger X5. I have, of course, read your writeups on both. Both get fine reviews everywhere. Although Rick Eutsler, when he tested the Stoeger, had a problem with the size and depth of the breech on his test rifle. He stated that about 65% of the pellets he tried would not go in flush with the breech and would then distort the skirt on the pellets when closing the breech/barrel. He did find some pellets that would fit and shot great in the gun, but was planning to remove some metal from the breech to fix this problem. His review is at http://www.airgunweb.com.
    What I like about the Air Venturi, from my reading, is that the internals are said to be just as if they had a tuneup before leaving the factory. One gent that took his apart and said the spring almost looked like it had been chromed it was so polished. You state that this gun, with it’s more modest velocity, should live a long life.
    I noticed that the mechanism that locks the barrel/breech to the receiver is different on each one. I’ve seen some cheaper models that use plastic for some of these parts. The X5 has a ball bearing, while the Bronco has a very stout looking post that locks it. Is one type better than the other?
    On another note, I have been working with my new Crosman 1377 all stock and with the open sights. I’m shooting so far from a picnic table and rest at 15′. Even with my bad eyesight I am getting some great groups. I have two equal groups using 3 pumps. One is the Gamo Match, while the other is the Crosman Premier hollow points. These are one hole groups just slightly bigger than one pellet hole. I tried reversing the rear sight and using it as a peep, but it made things tougher on me, though the groups were still very nice. The gun shoots so well with 3 pumps that I haven’t tried much more. I’ve wanted one of these for years as my Dad, who passed away in 1996, had one and loved it. He made life tough on the squirrels that came and ate the bird food my parents used to leave in their feeders. He was a life long smokeless powder shooter and taught me everything to get me started into a life of shooting safely.
    So anyway, I am leaning towards the Air Venturi, and I know you had input into the features of that gun. Everyone that owns one really loves them. I don’t need a lot of power. Accuracy is number one along with reliability. And I hear the trigger is great (this from a Crosman 1077 owner/shooter!).
    Take care, and keep up the fine work you do.
    By the way, I love air guns that shoot Crosman pellets well, as we have about no selection here and shipping $50 worth of pellets here from Pyramid costs about another $50!!
    Jon in Keaau, Hawaii

    • Jon,

      Wow! That was quite a comment. Any more and we would have to get you an honorary Matt61 badge! 😉

      As far as the breech lockup goes, the ball bearing works just as well as the chisel detent (of the Bronco) in guns up to FWB 124 power. So at this power lever, it’s more than enough. And a ball bearing breech opens easier than most breeches that have chisel detents, though the Brock is probably one exception, because it also opens pretty easily.

      I do think you will like the Bronco’s trigger quite a lot, once you get used to the different feel. It’s certainly better than the X5 trigger. And Premiers should shoot well in both rifles. I would say go with your gut on this one.

      B.B.

  15. Thanks for the information on the Bronco and not having to lube it. The rep at PA told me today I should put two drops of silicone chamber lube down the hole opposite the opening in the barrel. You may want to advise them before someone ruins a great gun. I assume it is okay to shoot some Beeman cleaning pellets once and awhile. Thanks for helping a newbie! Doug

    • Technically, you aren’t supposed to “shoot” the cleaning pellets, but instead push them through with a rod. The felt pellets may not provide enough back-pressure to cushion the piston of a spring gun.

      That’s not to say I didn’t use a few on my Diana m54 when I was adjusting the trigger — after a few unexpected releases I decided even a felt pad in the barrel was better than nothing.

      • Thanks! I made some minor tweaks and have been grouping very well. I usually push about four cleaning pellets into barrel before shooting.Artillery hold really works. I found a Civil War reproduction cap box on Ebay for 18.00. It goes on your belt loop and has a double flap so nothing is spilled. Holds at least a half can of pellets. Doug

  16. Off-topic …

    I am fortunate to have acquired a beautiful HY-SCORE Model 802 Repeater this week. It is just the pistol with no papers or box. Can someone suggest a web site where I might find owners instructions or a parts list? The seller dry-fired it twice and it seems to be ready to go. Any suggestions as to what I might do before I try it out myself?

    NRS

  17. B.B., Help me!! I bought the Bronco with optional peep sights based largely on your accuracy reports and I can’t get anywhere close to your results and I’m only shooting at 10 yards. This is a tale of woe and I won’t tell all, but in summary: The peep sight from PA was the wrong one, but they corrected the error with great professionalism; my bionic lenses (cataract surgery) didn’t work with the peep so I ordered a Merit adjustable insert which helped but still groups are not acceptable after trying quite a few round nose pellets of different weights (all the JSB match ammo available); I was still thinking the poor shooting was me and I ordered a scope which hasn’t helped, but has confirmed the problem is the rifle, not me. What to do? I was hoping you would have the answer in your follow-up report to the #4, but in response to my July 5, request you said No Followup. I am frustrated and I need help.
    All I want to do in punch out penny size groups at 10 yards using my silent pellet trap. Bob

    • Bob,

      I think one of two things may be happening. Or maybe it’s both.

      The pellet may be striking the back of the muzzle brake when it enters the rear. The sets up a flutter that destroys accuracy. If that isn’t it, the crown of the barrel, which is located deep inside the rifle, may be uneven. That allows compressed gas to escape at one side of the pellet before the others and that sets up a wobble that only gets worse as the pellet goes downrange.

      Have you talked to Pyramyd AIR about this problem yet? If not, I suggest you do.

      B.B.

    • Bob,

      in addition to what BB is saying, sometimes it helps to start with the basics. How do you shoot the rifle? Handheld, off-hand or bench rested? By hand held I mean are you holding the rifle in your hands and resting an elbow on a bench or shooting table? Off-hand I mean standing and holding. For these first two, are you practicing the “artillery hold” that BB has perfected and is always advising? For bench resting, have you placed your hand between the rifle and the sandbag or what ever you are using as a rest?

      If we can rule out these things, then we can focus on the rifle and BB’s thoughts.

      Apologies if I missed something previously that you are indeed familiar with the artillery hold and how BB obtains his groups. Also, this blog is over a year old and most of us do not monitor the older blogs. Come to the current blog where your difficulties will be viewed by thousands of very experienced air gunners and more help can be expected. Off-topic comments are always welcomed! We love to analyze and try to solve problems such as yours.

      Fred DPRoNJ

      • Fred, Yes, I have tried to use the best technique as demonstrated in the video. I will try again, then if not successful I will contact PA and start learning from you experts on the current blog. Thanks

  18. With my bronco I have found I can be deadly accurate and consistent with the original iron sights. I’m seeing many more flyers with a scope or the peep sight. What I was wondering is how many broncos out there have sideways movement in the barrel pivot point when the breech is closed. On my bronco I can grab the muzzle and see an air gap around the breech change when I move the barrel side to side. I have tried shimming but being a round barrel at this pivot point the shims don’t do much. Most other break barrel airguns have a flat sided block to pivot on. The broncos barrel diameter is the locating feature in the breech instead of the traditional flat sided block so you are locating to the peak of a round instead of two parallel walls. Any thoughts?

  19. Re: Pellet fit

    I had a problem with the breech of my Crosman Quest 1000X shaving the skirts on most of the pellets I prefer. I finally took a Dremel cone shaped aluminum oxide grinding stone and slowly and gently, repeatedly turned it by hand until there was a slight chamfer on the edge of the hole. It was a slow trial and error process to remove the sharp edge, but it worked and improved the Quest’s accuracy.

      • I’m getting about 3/8″ off the bench. I have a five-shot group in front of me now that was shot with the Quest, RWS Meisterkuglens and a Williams 5D that measures .305″. The first three shots literally went through the same hole. I thought I was missing the target with the second and third shot, but the cardboard backer moved a bit on impact and the hits were evident there but not on the target. The fourth cut the first three shots (.240″) and I blew it with the fifth shot for the .305″. I was concerned about chamfering the breech, but it helped a lot. If I concentrate more on the front sight and less on the target my off-hand groups at ten meters are respectable.

        Ron

  20. Re: The above comments.

    All my groups from the bench are at ten meters. My targets are usually 1″x1″ black target pasters stuck diagonally to the back of white junk mail envelopes. Paster are cheap and the supply of junk mail seems never ending. With scope or iron sights, when you hold on the bottom peak it is easier to control vertical aim than on a round bull.

  21. That’s not bad. The Quest is sometimes iffy, but (as you are finding out) a good one can be quite respectable. Have you ever worked the action at all to tighten the breech or improve the lockup?

  22. Lock up is still tight after much use. I installed a 8.5×3.5x5mm bushing to improve the trigger, and did a tune job on the compression chamber and spring a couple of months ago after the factory spring broke. Put in too much heavy tar and had to disassemble and remove most it to eliminate dieseling. I would like to find a way of installing two smaller springs, coiled in opposite directions, to see if they would eliminate torque. With the tune and bushing I like the Quest better than my Vantage NP for off-hand shooting.

    FedEx just dropped off an Air Venturi Bronco that I have to check out. The rear sight is sturdy but adjustments are crude. Fortunately I have an extra Williams 5D to replace it.

  23. Because of the way the Quest is shooting, actually easier off-hand than my Vantage Nitro Piston, it wouldn’t benefit me to convert. I am just curious as to how opposing twist would react. I have a Walther LGV Special that uses opposing pistons and it is a pleasure to shoot.

    The Bronco is very accurate, but the front sight is much too low and stock design is not the best.

  24. Reference my post of August 5, 2014, 11:30 am.

    Seems my ideas are always late. I found the following on network54.com:

    “In 1968 Walther’s introduced its ultimate match springer with the LGV Special (or in German, the LGV Spezial). The LGV Special has the leaded stock like the LGV, but added two short springs wound in opposite directions, an improved match stock, an adjustable buttplate, and an even more refined adjustable trigger (major difference from the LGV is an adjustment for length of pull). Many feel the LGV Special is almost Feinwerkbau 300S like in its firing behavior, neatly eliminating the twist and most of the vibration of a single spring.”

  25. bb,
    really sorry man but now that you no were my post is,i think that i will post i t here.
    i see you have been casting bullets all the time therefore how about casting a.177 cylender i mean just a cylender!.push it with a dowell about half way from the breech and back by using another dowell push it back.if there is any mark on the cyleder other then the rifling then you proved your point this was with the back(notch) sight

    you can even try this with the muzzle to clarify the front sight ase well

    • Utkarsh,

      No, that won’t work. I am saying that the pellet is hitting the screws AFTER is exits the muzzle. The barrel is shorter than the outside tube that’s on the gun. It ends many inches before what looks like the muzzle.
