In this video I use my Air Venturi Avenger 22cal to show POI changes and how to fix it, same pellet and same muzzle velocity on target! Haven't noticed it so much in 25cal....

[@diggernash1]

I must have won the regulator lottery. I shot a 115 shot string yesterday and manage a 1.2" group at 38 yards. 5 shot groups are under 1/2" with plain jane crossman brown box 10.5s. Velocity trended downward from 901 to about 880 and SD of 8 on the FX chrono, with the bottom end being less stable after I dropped below reg pressure. By 120 shots it had dropped to below 850 fps and I stopped. I would estimate that 95+ of the pellets strikes(shooting freshly painted steel) could be covered by a quarter. And most of those grouped tightly in the center. I'm still amazed at the performance of this budget gun compared to my .25 marauder and .22 flash pup. Both of them shoot extremely tight groups, but you get 30 or so good shots with the .22 and 20 with the .25; 110+ shots between fills is in a different universe. I will be able to take this thing to the deer woods with me this year and wreak havoc on armadillos and squirrels for the entire weekend between the white tails. My tune is 1600 reg(according to the stock gauges that I don't trust) and about 3/8 of a turn in on the hammer spring. I'm not settled completely on this, as I have the gun filled waiting for testing tomorrow at 1/4 turn out; as velocity was still descending slightly

[@heithwatkins]

I keep my 177cal Avenger set around 1,100 reg pressure. I have a slow descent in fps from 4350psi to the 1,100psi. Overall the SD remains within 10fps. I use this tune for hunting in woods from 10 yards to around 40 yards. The shot count is around 150. This is also a great tune for 25 yard target shooting. The reason the shot string descends is because the factory hammer spring is too strong for my reg setting, even at its lowest. However if I raise the HST it will effect my first shot using 10.5gr crossman ultra mags. This is no problem target shooting. But hunting is another matter. I can't set up my rifle for 900fps because the reg will creep a little and then I may shoot 20fps faster after letting my rifle set 15min. This makes my 10.5gr unstable and I may miss the squirrel. This 20fps faster first shot won't matter at all if I tune for 850fps. So that's what I do. If I desire more power. I use 13.43 to 16.2gr pellets. Then I can turn up HTS with no issues. But those 10.5gr crossman ultra mags are only $11.49 per tin of 500. They are cheap and accurate. Pyramid Air gives the 4th tin free when I buy 3. Sorry for the long post. But I hope it helps people.

[@tommanfs6843]

Absolutely correct .....i never experienced "dramatic" poi shift on my .25 but did notice if i only fill it to 36/3700 psi (reg set at 2300) thats where my shots are more accurate, down to about 2100 before noticing some fall off. Shot count is not an issue for me because im never far from a fill source. Thank you so much for these videos ....... youre helping many people ....stay safe and happy shootin !

[@sberrett]

I’ve had the Avenger in .22 for about a month now and was dealing with this issue. I was max filling and after every fill my POI was off by alot. Very annoying. I asked around other forms and after hearing the same thing you’re talking about, i lowered the regulator pressure and have been filling to about 3600-3800 now, and additionally added a black arts band kit in addition to the donny fl barrel adapter. My POI shifts are gone now. It sucks that you cant use the gun for what its rated at in regards to max fill, but i’ll gladly sacrifice shot count for consistent accuracy. It was a headache when I first got the gun and if I knew what I do now, I probably woulda went with dreamline. Great vid though.

[@Barlas511]

Agree. I am an artillery man. At 10 kilometers or more the effects of so many factors do come in, though the projectile is so heavy.

[@ALLABOUTAIRGUNS]

Awesome!

[@mauricenations7511]

Thanks James for another informative video. Keep on doing a good job of keeping up with peoples needs on air guns.

[@ALLABOUTAIRGUNS]

Thanks for watching!

[@jrhill3082]

Awesome Info....I figured this out recently, so I keep my pressure at 250-260 bar.....actually I think you mentioned this in one of your videos, but it was for unregulated versions, similar & effective. 👍

[@ALLABOUTAIRGUNS]

Thanks man!

[@JamesKing2understandinglife]

Thank you for doing so much shooting investigation for us.

[@tempoford3283]

ABSOLUTELY PERFECT THANKS J.

[@ALLABOUTAIRGUNS]

Thanks!

[@joshuagibson2520]

This was a really good video and conversation on airguns.

[@ALLABOUTAIRGUNS]

Thanks, I need to do more videos like this

[@shawnthelocksmith9405]

James, I think those .22 pellets are hydroplaning..or not. I found it pretty cool that you touched upon the fill pressure of 2x's the reg. I found this out on my little .177 Stormrider. I set the reg at around 90 bar and noticed a BIG Poi at 45 yards. When the fill dropped down to 160-170 ish, poi was where I started with my sight-in. So now I only fill to a max of 2650 and.....wait for it........Dead Squirrel. Great Info, Thanks

[@ALLABOUTAIRGUNS]

Thanks!

[@richperdue9344]

My Avenge X has POI shifts. It's from the barrel being tied to the shroud. Totally free floated my Marauder for same reason and that fixed it.

[@wadedeeds1738]

I use 18.13 in 22cal. No problem. 25.39. In my 25. Js. Another great video James.

[@moetown909s3]

Yes thanks

[@moetown909s3]

You a big help thanks i was thinking if i set reg at 1900 i can fill to 4000psi an i knows when zero scope an come back next day its off

[@sandyschupper8401]

If the POI shift is as you say due to regulator pressure versus fill pressure; why would there be other than vertical dispersement?

[@vamonosdecaceria5005]

many, many thanks brother my question is resolved

[@ALLABOUTAIRGUNS]

Thanks for watching!

[@sirjhonson8218]

Have you ever polished the barrel with a cotton gun swab and jeweler's Rudge

[@juliofranco9244]

Great info thanks

[@ALLABOUTAIRGUNS]

Thanks!

[@gumbystown]

I've experienced POI shift with my Avenger in two different ways one is temperature if I start shooting my gun at early morning where it's like 45° out and I keep shooting the gun throughout the day until it gets to be 90 ° out there will be a POI shift usually I've just guessing it's usually always to the right and I will turn it a few clicks to the left and the POI shift will come back to where it was and then towards the evening when the day starts cooling off the POI shift will shift back to the left and be off Target and I've experienced what you were just talking about there with the different fill pressures.

[@ALLABOUTAIRGUNS]

Yea I'm trying to narrow the vertical poi shift now it's either crosshairs or 1 mil dot or 2 mil dot high at 25yd

[@spartanslugs8765]

Did you figure out what is the problem when it shift right and then later on it go back to its usual zero ?

[@gumbystown]

@@spartanslugs8765 No I haven't really came to a conclusion of why it does that. I've talked to quite a few different friends that have Avengers and I don't know no some people say it's because the actual air tubes expand when they're under full pressure which makes the barrel bands shift a little bit and change your point of aim then some people talk about the temperature making the metal expand and making your point of Aim shifting and and some people talk about the different temperatures and pressures affect the functioning properties of the regulator?

[@spartanslugs8765]

@@gumbystown i have the same issue with my impact M3 , so i think it is not exclusive for the avengers ,

[@sirjhonson8218]

I will always pick the .25 cal.

[@christianjones4691]

What's your regulator and hammer spring setting? Thanks!

[@igolfat8894]

If you are using CPHPs with a 2200 reg, what velocity are they going?

[@WillievanGraan84]

I have the .22 Avenge-X. My question is, if I set the reg pressure to 2500PSI and I fill the gun all the way up. Will this issue be gone?

[@derrickmitchell39dm]

I got a 4500 psi, 700cc bottle on my fx mk2 .357. What should be my regulator setting?

[@jmanting]

James, my Avenger .25 froze up will shooting this winter. I tried refilling the tank and air came out all over. After sitting over night I was able to fill it but noticed I had to do it really slowly to avoid air escaping. Since this happened my POI is all over the board. This gun was a tack driver using the factory tune and H&N Barracuda Hunter Extreme pellets before this happened. Any thoughts?

[@rossfrid3159]

James, I wonder if this could be true with high volume air bottles like the RAW or FX Avenger? Seems like this may be true with those as well. I have been struggling with why my RAW might shoot higher or lower on certain days. It’s worth keeping tract of the humidity.

[@ALLABOUTAIRGUNS]

Yep! I'm currently working on solving it once I do I'll make a part 2

[@frankcross2297]

I’ve seen a post about the Avenger stock interfering with the power plenum area causing stress.

[@washou5012]

Thanks

[@user-ki1gq3eu4o]

Do you think hatsan is better for hunting?

[@CazaVideos005]

I had been having some big poi shifting between fills (about 5 mildots horizontal and 4 mildots vertical), what can possibly be? Also, do you recomend adding a second barrel band and donnyfl barrel centerer/ silencer adapter?

[@ALLABOUTAIRGUNS]

Check barrel shroud gap between air cylinder...if it's evenly spaced then I wouldn't worry about adding another band but if the barrel shroud is touching the cylinder or not even get another barrel band...another trick to try take 5x shots to reset reg and see if it helps, I have very minimal vertical poi shifting now...check pt2

[@back_roadsairgunning2200]

Since the Avenger also has a hammer spring adjuster, could one mark a setting for full fill pressure, and one for lower tube pressure as the gun is shot down. Or is there a gradual climb of POI as the tube pressure decreases ?

[@ALLABOUTAIRGUNS]

Velocity is same it's just when in my rifle hits a certain pressure level it drops or goes higher

[@dow4hurst]

Gonna try this out with my bullpup 22 ava.

[@ALLABOUTAIRGUNS]

Let me know, my bullpup is 22cal and set 2200psi

[@jimmendoza4625]

​@@ALLABOUTAIRGUNS what about the hammer spring at what?

[@vamonosdecaceria5005]

James’s dicen que con un poston liviano no ase cambio de poi

[@johnnyventurino8947]

James I have a LESHYI CLASSIC and my Huma regulator is set at 120 BAR and I fill it up to 240 BAR and I notice Poi shifts sometimes so what Bar pressure do you think I should fill up my gun to buddy.

[@ALLABOUTAIRGUNS]

I would say try around 3k psi/200bar see what happens

[@johnnyventurino8947]

@@ALLABOUTAIRGUNS ok thanks James I will try that buddy.

[@MrTyroneweaver]

I have an Element Helixc 6-24 on a FX Compact and whenever I change power I get a horizontal shift.

[@ALLABOUTAIRGUNS]

Something isn't right there

[@Jeeper1378]

Fx Panthera hunter in 22 same scope.. never poi shift’s like my AVA x. Never had a gun until this one that changes 4 times during a shooting session.

[@mrabc12345678911111]

I have both calibers and I still have POI even with a high 2900 regulator pressure Every day I take it out I have a different POI

[@cheryl678]

Im at 24oo and I don't fill past 4000psi is that too high or should I bring it down to the 2200 that your using???

[@ALLABOUTAIRGUNS]

Should be fine if you dont notice any problems

[@lamardaniels6625]

Quick question...Pyramyd Air said they could PIWER TUNE this same rifle to increase it for a lil more FOOT POUNDS ENERGY...But from ta experience with the rifle prior to tune up, will this take crows 40+ yards in 22cal???...and what is the true fpe???

[@ALLABOUTAIRGUNS]

It'll take crows no problem can't say on exactly what fpe they go by

[@verdellparentaaawink268]

Hey james can you do some tests on the penetrator rounds I make for the 25 cal..I have a video on how to make these on my KZbin channel...thanks for the poi info it makes sence.. at the factory regulator setting of 2900 psi double that and you get 5800 psi well above the fill pressure of 4300 psi..a 1500 psi difference...so at 4300 psi fill minus 1500 psi equals 2800 psi ....so if your regulator is set at 2200 psi double that you have 4400 psi minus 1500 psi will bring your total fill psi to 2900 psi...just a theory.....so if your regulator is set to 2150 psi double that and you get 4300 psi then minus 1500 psi you will get a fill pressure of 2800 psi

[@eddiecahall3824]

And put a barrel stabilizer/harmonics in the shroud and barrel lock band from Terminador airguns and outdoors duhhhh

[@juliotapia4098]

Saludos desde chile , lo felicito por sus videos, quiero hacer mi humilde aporte yo tengo mi avenger Bullpup.22 y al ver los videos creo que su seteo está errado . Yo lleno mi rifle hasta las 4350 psi y mi seteo de válvula está en 2200 psi y el resorte de martillo en una y media vuelta y dispara con JSB 18.13 a 865 FPS y me da 85 tiros regulados a esa velocidad. Y agrupa a 50 yardas en 1/2 pulgada .
