.25 cal POWER!

[crazyaust]

what fps/fpe do you like to shoot your .25?

I’ve been messing with my regulator pressure a lot and can’t seem to find the best leave it there spot yet.

I have the leshiy 2 with 350mm barrel shooting around 170 bar at around 60-65fpe I have a few different ammunition that’ll give me very different results and speeds but my goal is to tune it to a very powerful, efficient state where I can throw it in a backpack go hunting for the day and not to refill my 300cc tank so far air efficiency hasn’t been a problem I can get around 40 shots before I drop below 130 bar out of this 350mm barrel not too bad. Also have some issues with groupings but yet it’s hard to really solve that since I have a crappy scope so not sure if it’s the gun or that But I figured I need to start with jets. Maybe sizes .2/.2 and another pair of .5/5 and try those two sizes out but I also can’t get my hands on them.. anyway
I’m not too sure how other guns regulate pressure but some info on .25 cal what what’s best Speed to shoot them at and how you like to save air etc..
I’m currently shooting avs 254 34gr and hades 26gr

Got my .25 Avenger up to 83 FPE using Seneca 43.2 grain pellets. JSB 33.95's I can push to about 73 FPE. Not many of the slugs get much over 70 FPE due to the slower nature of them from my gun. Testing about 20 different slugs to see which one will reign. But it's hard to beat the jsb pellets for accuracy. Really wish someone made a jsb copy that was about 40 grains. I think that would be the ticket from my gun.

.25 Taipan Vet Standard - 50gr AVS HP/BTs @ 930fps = 96fpe

was running 48gr @ 980 for 102fpe but the 50s seem to be a bit more accurate

20shots @ 75yrds - backyard is limited - fell off the regulator there at the end

I modified my armada .25 and set it to shoot 33 grain varmint knockers at 920-940 for 20 shots. It will crank up to over 94 ft lbs with 48 grain slugs but I have .30 and .357 if I need to get there . It will run from 40 -65 ft lbs pretty efficient. 1.7 on a hot fill.

I.m putting JSB 33.95's out of the Huben @ about 920 and found this to be the sweet spot. No choke though.
