Today I keep my word by testing the AirVenturi Avenger at lower fill pressures — say 2,500 and 2,000 psi. My thanks to reader Brent who reminded me of this test.

Summary

Let’s skip to the end — I hope. Filling this regulated air rifle to a lower pressure should be exactly like putting less gas in a car. It should still go just as fast — but not as far. In this case the Avenger will get fewer shots on the fill but the velocity and accuracy should remain the same, give or take. I won’t test the accuracy again until the 50-yard test, but today we will look at the velocity.

What we know

In Part 3 we discovered that the Avenger is still very powerful when the regulator is set to its lowest setting and the hammer spring that is also adjustable is set to its lowest setting. When everything was set as high as it will go the power was in the 36 foot-pound range and there were a total of 55 shots before the rifle needed to be refilled. When everything was set as low as it will go the power was just under 25 foot-pounds and the rifle gave 96 shots before I stopped shooting. With so much adjustability we can argue whether there are even more useful shots on a fill but at least there are this many.

What we learned is the Avenger is very careful with its air. We also learned that on the lowest power settings it is extremely accurate, besides providing decent power. That makes today’s test a valid one.

Why are we doing this?

We are testing this concept because the 300 bar fill the Avenger requires is beyond the ability of many who want to own the gun. To get pressures that high means they either have to have a 4,500 psi carbon fiber air tank or a compressor, or both. In recent times the cost of compressors has dropped dramatically, but carbon fiber tanks have remained expensive. The Avenger retails for just $300, so the shooters looking to buy one are probably not willing to spend the extra $700-1,000 to get everything they need. But if the rifle can be filled conveniently with a high-pressure hand pump and if they get a reasonable number of good shots from it then the need for all that stuff goes away.

We don’t need to test the gun on low power and again on high power. Whatever it does at one power level it will do at all power levels.

The test

I wondered how to proceed. Should I empty the rifle and then fill it with a hand pump? I could do that, but what would I gain? 

When I looked at the onboard gauge it was reading just under 3,000 psi. That was left over from the test in Part 6. So the airgunner in me did the easiest thing — I released the reservoir pressure until the onboard gauge read 2,500 psi.

Avenger bleed screw
The 3mm bleed screw releases air from the reservoir.

I released the air very slowly, watching the needle on the gauge carefully. I know that these gauges take time to settle in so I gave it plenty of time. When I finished it looked like this.

Avenger gauge 1
The test was started with the onboard reservoir gauge reading as close to 2,500 psi as possible.

Is it still on baseline?

First I wanted to fire 5 JSB Exact Jumbo Heavy pellets to see if the Avenger was still shooting at the velocity recorded previously. In Part 4 we established the average velocity at 782 f.p.s. at this lowest power setting, with a spread from 768 to 790 f.p.s. We learned that by waiting for the regulator to fill the velocity did increase, so there was some special testing done (waiting a full minute between shots) to get all 96 shots last time on a fill. I may need to do some of that today and I will tell you as the test progresses. Now let’s look at the velocity of 5 JSB Jumbo Heavys with a minute between each shot.

2500psi fill

Shot……….Vel.
1…………..793

Then I shot the second shot while waiting only 30 seconds after the first.

2…………..769

After that I waited at least 60 seconds between shots.

3…………..777
4…………..775
5…………..771

I am almost out of JSB Exact Jumbo Heavys so I switched to Beeman Kodiaks to continue the test. Also waited 60 seconds between shots.

6…………..712
7…………..704
8…………..698
8…………..709
10…………704
11…………699
12…………702
13…………717
14…………710
15…………708
16…………708
17…………707

Now I shot one JSB Exact Jumbo, just to show where the rifle was.

18…………772 JSB Exact Jumbo

Back to Kodiaks.

19…………716
20…………707
21…………714
22…………719 
23…………718

At this point the onboard pressure gauge read exactly 2,000 psi. So from 2500 psi down to to 2000 psi I got 23 shots that were consistent.

Avenger gauge 2
When I started the shot string that follows the gauge read 2000 psi.

24…………710
25…………703
26…………698
27…………714
28…………706
29…………702
30…………709
31…………707
32…………702
33…………705
34…………699
35…………703

At this point I fired another JSB Exact Jumbo Heavy, just to check.

36…………771 JSB Exact Jumbo Heavy

And back to Kodiaks.

37…………703
38…………711
39…………700
40…………711
41…………698
42…………703
43…………701
44…………699
45…………694 off the power curve
46…………710
47…………695
48…………695

That’s 21 shots on 2,000 psi and another 23 if you go up to 2,500 psi. If you can pump to 2,500 psi you get 44 good shots when the rifle is set to the lowest power settings. The pressure gauge had just dropped off the green when the power curve ended.

Avenger gauge 3
When the power currve was through the gauge read like this.

Highest power?

We got 55 shots per fill on the highest power settings and 96 shots on the lowest settings when I filled to 300 bar. So, take the numbers in this test and chop them in half and that’s roughly how many shots you’ll get when shooting at the highest power and filling to these pressures. 

Notice that filling to 2,500 psi gives a lot more shots than filling to 2,000 psi. So, if you fill with a pump go as high as you can.

Summary 2

The Avenger gives a lot of useful shots even when you don’t fill it all the way. I don’t know what else I can test — other than accuracy at 50 yards which is coming. I think this air rifle is the best buy of the millennium!

      • Yes, and I looked at all 23 posts.
        One is a gift guide for Christmas, where BB reccomends a pump as a possible gift.
        Two is about hand pumps for the ancient big bores.

        There is no review, that I can find, that highlights hand pumps for PCP’s. One sentence that mentions “hand pumps” might be enough to get on the categories list, but not enough information about the good, the bad, and the ugly…

          • Yogi

            Glad your asking.

            I been seeing you trending towards questions about PCP’s.

            Maybe one day? Or you just see what all is involved.

            All I can say is one day I i hope you try them. They really aint that bad.


          • B.B.

            It would be great if you could review the top 3 selling pumps. Would your bathroom scales that you use for testing cocking effort work with hand pumps?
            Then compare the “work” involved in pumping up an efficient PCP, like the Air Venuri Avenger for 100 shots. Compare this with the “work” involved with cocking an efficient springer for 100 shots.
            Which is harder work?
            My brother knows how many floor pumps it take to fill his bicycle tires to 120 psi.

            -Y



              • B.B.

                Basically, what gives a harder workout 100 cocking of a springer or 2 to 3 fillings of a PCP tank by hand pump? Which burns more calories? lol.

                Thanks,

                -Yogi


                • Yogi,

                  I am not sure that what you are asking is even realistic. Off the top of my head,… I would cock a springer 200-300 times before I would pump up a tank,.. which by the way might be 200-300 pumps with (full) body workout.

                  “…. or 2 to 3 fillings of a PCP tank….” ? ,……….. define “tank”. A 200 cc tube on gun? A 500 cc tank on my Red Wolf? A 98 cu. in. CF bottle like my Guppy? A big 98 cu. ft. CF tank? How low are any of them and then,… what will be your end pressure?

                  I could probably come up with more scenarios,… but I won’t. To me, a hand pump is a budget way to fill directly to the gun.

                    • Yogi,

                      Early in my Dark Side career i used hand pumps exclusively to charge them. It is a great workout! FROM EMPTY: The first 2,000psi are a slow build up to a load similar a bike pump. Then it gets progressively harder and at 3,000psi and beyond it takes technique to use all your body weight on the handles. If you grip the handles too had you can mess up your Carpal Tunnel so don’t grip the handles tightly and don’t cock your wrists. I also learned early on you need at least two pumps so one can cool while you keep pumping; otherwise it takes a long tome to fill a 22 Cu in bottle to 3,000psi. I used FX, AXOR and Hill pumps starting with generation 1. They have gotten better with each generation and are rebuildable. Rebuilds are required most often because of overheating not because of simple material failure. Pump quality/function seems to be directly equal to MSRP.

                      I will offer you an alternative fill method, used 110 Cu Ft steel dive tanks! If you have a dive shop near you they can all fill to 3,600psi which the steel tanks are rated for. I have two that are 50+ years old! You can buy one used and a new valve and fill hose/QD for less than two hand pumps. You dont need filters and moisture traps because the fill will be DRY CLEAN BREATHING AIR!

                      Hope that helps,

        • Yogi,

          Well,… you dug deeper than I did. Buy the best you can afford (the good), be prepared to maybe pump more than shoot (the bad) and maybe it will break and leave you high and dry (or) you say * this and get an automatic pump (the ugly),…… just from what I have gathered. 😉

          Chris



            • GF1,

              Sure,.. I want lot’s of things. A nice ’60’s/70’s hot rod. Do I need one? No. Can I afford one? Probably. Can that money be used better else ware? Without doubt.

              Live within your means, do the best you can with what you have, saving is better than spending, be thankful for what you have, count your blessings.

              Anyone of those points have their trade offs. Do your homework to stretch your $ and pull the trigger when/if it comes time to buy. Everyone has (their own) parameters that they must work within. Some are very limited, some are unlimited,… with everything in between.

  1. BB,

    ROTFL! You sure look cute in that cheerleader outfit with those pompoms! You most definitely are being “The Great Enabler” today!

    I was sold on this air rifle long ago. Nova Vista and Air Venturi are going to have a hard time keeping up with orders for quite some time. Who needs to change calibers? Just change air rifles, it will be cheaper.

    From everything I have seen, heard, read you can buy a better shooting air rifle. It will cost you though. Straight out of the box, the price difference between this and the next serious competitor is staggering.


  2. RR Is your Avenger on its’ way or do you have to wait until Sept? My air gun fund changed from the Dreamlite to this. I’ll be shooting an Avenger much sooner than a FX.


    • Rk,

      It may be longer than September for me. My airgun funds are pretty lean right now. Both BB and myself have shot a Dreamlite. Neither of us was impressed. You can buy all three calibers of this air rifle and still have some change for what one of those things cost. FX had their chance with BB and FX had their chance with me. I will take this Chinese airgun first.


  3. B.B.

    You have just said and proved what I have been saying for a while now (I just substituted the two capitalized words because this is true for all regulated air guns)…

    Filling (this) ANY regulated air rifle to a lower pressure should be exactly like putting less gas in a car. It (should) WILL still go just as fast — but not as far”

    IMHO, if you are designing a PCP, it makes sense that it should be designed to handle (the current typical maximum pressure of ) 4500 psi. Over filling would not be a problem, maximum power (for slugs and/or pellets) and shot count is possible.

    Agreed that not everyone has the equipment to fill to 4500 psi but with a regulator, SCUBA tanks or hand pumping are still viable options as any pressure over the regulator set-point will yield consistent velocity.

    Being retired and no longer commuting to the big city to fill my air tank, getting a compressor made a lot of sense. Having unlimited HPA (with no worry of running out!) and considering the cost of time and gas it was an easy decision.

    The price of a HPA tank and compressor is pretty steep relative to the Avenger but if you shoot a lot or have a number of people in the family or group the cost can be more easily justified or deferred.

    Just saying.

  4. BB, The externally adjustable regulator is the most significant feature of this product,
    and in the years to come, it will be on many others I predict. My Prod cost $350. and that was before
    it got regulated. I like the degassing screw on the Avenger, nice touch. Companies like Crosman may need to scramble to regain market share, but I wouldn’t worry too much, we’ll just have to wait and see what they come up with. How about a nice side lever on the very light and handy Marauder pistol, to go with an externally adjustable regulator? Mine gets about 25 shots or so @735 fps at 1600psi. 12″ barrel. My point is it wouldn’t be too hard to make Crosmans’ old product more relevant by adding some features, but I still can’t make up my mind about .177 or .22 as far as the Avenger goes. One of each, or a nice scope..or a compressor. I’ll just drag out the R10 and think about it some more. Happy shooting!
    Rob


  5. BB, I guess I know what I want for my birthday later this year. You are really beginning to tick me off! Enabler indeed!!! LOL

  6. Shouldn’t accuracy be the most important thing? Is a .22 PCP or a .22 magnum springer more accurate shooting at a target 50 yrds. away? Marauder or Diana 48, for example… Or is a .177 CO2 or a .177 ~7-10 J springer more accurate within 30 yrds. on a Summer’s day? On a lovely 90 F day if an 850 is more accurate than an R7, then I’ll choose 850 over R7 without a second’s hesitation. Would I be terribly wrong? I mean do we call R7 a great gun with great accuracy ‘just because’ it’s accurate ‘for a springer’ – despite the fact that an 850 might kick its butt on a warm day for being a CO2? If that’s the case, then 850 is without a doubt more accurate than R7. Would’t that conclusion / assumption make R7 a good accurate ‘springer’ – not a good accurate rifle? Just a general discussion about airguns…


    • Diana Grl,

      PCP’s are just much easier to shoot well, quicker. Name your power level. Not as hold fussy. CO2 would be near the same,.. but not likely to match PCP power. Springers are nice in that they are self contained. If I were considering a springer again,.. I would also look into single and multi-pump pneumatics.

      Chris


    • Diana Grl
      Yes accuracy is most important. But so are other things.

      Its a balance.

      It all has to come together.

      That’s when you will find you will be most happy. That is if you don’t drive yourself crazy getting there. 🙂


      • The crazy train has already left the station!?
        I’ve been in the market for a new airgun for quite a while, and finally made my decision. This is just to learn from others’ experiences and such…


        • Diana Grl
          Oh I know.

          I learn a different way. Probably more expensive. But at least that way I know personally.

          Just the way I always been. I like exsperiance. 🙂


          • I’ve never spent a dime on a low quality product. I only buy one, and use it for long years. My guitar, amp, car, motorcycle, camera, sailboat, and air rifle – only had one of all those. Just because I’m good at something, doesn’t mean I should buy a dozen of it. I do my homework before putting money into a product; yet, I’ve never regretted buying any of my possessions. Also I have fun talking about my hobies and meeting other people with similar interests.


            • Diana Grl
              Definitely different.

              I always like having something new go on.

              But I always learn the most out of everything I encounter.

              Call it a curse. Or call it a blessing.

              All I know is I enjoy everything I learned. Hands on.


              • A guy can have a 12 ga Browning, an 8mm Mauser, and a .22 Marauder. On top of those, he can even buy an R7, and I’d say money well spent. But I met people who has 2 HW97s, 1 HW77, 2 Dianas one 48 and the other 54, a couple of 34s, one R9, and 3 R7s just for fun. And then you’ll find him shopping for a Hatsan magnum springer. 😀 If a rifleman has only one good rifle, then his brain will have a milimetrical memory of how to shoot it. When ever he grabs it, his brain will know what to do with it. Like playing a solo on a guitar or riding a bicycle, the brain will automatically put the hands, fingers, and such where they have to be – the breathing and other details would be just for that rifle. If one has a dozen of different rifles for the same job, then the brain won’t develop that consistency; the rifle won’t become a part of the body.


              • Gunfun1, we just disagree, and it’s cool. It’d suck if everybody agreed with me. Thanks for sharing your thoughts. I’ll keep them in mind. Take care.


            • Diana Grl,

              Very smart and wise. And,.. by not having 1,2,3,4 of something,.. allows more money to get a “fine” something else. +1 on doing one’s homework. That can save a ton of $ right there!

              Chris


              • Very difficult to do nowadays, with all the new marketing trends. At least, in the air gun world, still can be done to an extend, all thanks to German producers… 🙂


    • Diana Grl,

      I have an HW30/R7 here. It is awesome all year long. Your CO2 air rifle is pretty much useless to me about half the year because it is too chilly around here for that. If I lived in Florida, I might not feel that way, but I don’t. I also like the total independence of the HW30/R7. No extra capsules or tanks or compressors. Just pellets and air rifle and away you go.


  7. B.B.
    Thanks for this report. I fill with a hand pump and for that reason give the higher pressure PCP’s less consideration. Your test showed that a lower fill can still give a reasonable number of shots. I would be putting this one on preorder if my Gauntlet were not here to fill that nitch.
    Gerald



      • Agreed on both points. Having the bottle that comes off was a fix when mine would not take the first fill. It needed a blast of air to close the firing valve. I like the many shots it has between fills. I don’t have an exact count because I add air after 5 or 6 magazines. There are more shots left in the gun but it is less work each time to pump it back up sooner.
        Gerald


        • Gerald
          Yep just like that.

          I keep wanting to get a .25 Gauntlet but I already got a good .25 caliber gun.

          I guess I’ll just have to miss out till I try it.



  8. Today I decided to test three of my multi-pump rifles and do a bit of a comparison. The three I tested are the newest ones.

    1. A Benjamin 392 no longer available, it is now sold with a synthetic stock and pump handle. I am not sure if the stock is the only difference between the 392 and the 392s.

    The 392 with Hawk 3-7 non illuminated and wire reticle cost $337. It weights 6 lbs 14 oz. I shot it with 6 pumps/shot for 10 shots. It is hard to pump with a scope on it because the scope mounts clamp on a breech that is soldered to the pump tube and can come loose with any force on the scope. I must be getting weak shooting pcp’s to much the 60 pumps wore me out. I used to do hundreds of pumps in a session with out a sweat. The easy way to pump is to sit in a low chair and put the stock between your feet and pump while holding the muzzle end of the gun in your off hand. That requires getting out of your shooting position every shot so I pump holding the stock behind the trigger guard with my off hand.

    2. A Seneca Dragonfly that also no longer seems to be available. That is too bad It has many features that make it a very good multi-pump. Quality control did not seem to be up to snuff. A 2nd gen gun could have be very good.

    The Dragonfly with Hawk 3-7 non illuminated and wire reticle cost $300. It weights 7 lbs 1 oz. I shot it with 6 pumps/shot for 10 shots. A total of 60 pumps for 10 shots. It is hard to pump but with a solid breech and dovetail I hold the gun at the scope with my off hand making it easier. I may pay the price someday if the breech loosens on it.

    3. A Seneca Aspen this is still available and is really a hybrid pcp and multi-pump. I don’t consider it a pcp because it needs to be pumped up after only a few shots to maintain consistency in velocity. I don’t see that as a problem.

    The Aspen came in a bundle with a fixed 4 power scope. The scope has AO, non illuminated and wire reticle it is adequate but inferior to the Hawk scope on the other two guns. The bundle cost $300. It weights 8 lbs 15 oz.

    I shot it on low power. I started the 10 shot group at 3000psi after 3 shots I pumped it back up to 3000 psi with 7 pumps. in the third set I shot 4 shots so it took a total of 21 pumps for 10 shots. That put the gun reservoir back to 3000 psi after 10 shots. For this gun I sit in a low chair and hold the stock between my feet the muzzle in my off hand and it is very easy to pump.

    Summery: I think this is the first time I shot all three of these guns on the same day. I must say the Aspen is the better of the other two. The trigger on the 392 is by far the worst. The triggers on the other two gun are both good. Relatively light with a little creep. Based on the cost even adding $150 for a better scope down the road, the Aspen is better, for the extra 2 pounds you get a nice gun. In comparison my Marauder with the wood stock and large scope weighs 9lbs 15 oz.

      • Benji-Don,

        Wind or no that is nice shooting at 25 with Multipump!
        I agree that TCFKAC made a big mistake not building the 39X with a strong scopeable breech with a freefloated barrel a few years back! I have one of the hybrids with the scope dovetails that they offered briefly as a X/500 run and it shoots lights out for a P392.

        shootski


        • I really don’t see why a multi-pump cant be just as accurate as a pcp in the smaller calibers. At least out to 30 or 40 yards. I got a 1.27 inch group at 53 yds with my modded Crosman 1322 with a Maximus barrel. That was pushing it with the small pistol valve.

          What would a 10 meter single stroke pneumatic do with a multi-pump valve large enough to throw some heavy lead?



  9. BB,

    Thanks for doing the test at 2000 psi. The shot count was pretty much the same as my maximus euro from 2000 psi down. The Gen1 Marauder trigger that I had tuned is actually much better and I don’t think the accuracy is going to be significantly better at 50 yards.I think I’ll stick with my Maximus and save up for the Diana M1 Garand or the Marauder semi auto.

    Brent
