So I just recently purchased an airgun again after selling my Huma regulated Wildcat that I had years ago (I miss that gun, it was amazing...). Any who I really wanted to build something on a budget that could generate near my wildcat's powers to shoot some slugs out of it. My wildcat was tuned shooting 60 FPE with 33.95 JSBs for a ton of shots I don't remember exactly how many but close to 30 if I recall. Now I'm not looking for the wildcat's accuracy nor it's shot count as I know I won't get it. What I am looking for is to shoot these NSA 33.9g slugs that I bought @ near 60 FPE (58-60). If I can get even 10 shots with it with a low spread I'm happy and that's not a joke haha. So I purchased a huma regulator in the XXL plenum and I'm hoping to set it and forget it. Anyone with experience with this rifle want to let me know around what bar I should be setting it to? Hammer tension wise how many screws in? I know it's all relative every gun is different but a set point would be nice, I heard a guy reached 80 FPE so I know it's probably possible. Probably.. haha. Thanks everyone!
Hatsan Flashpup .25 60 FPE possible with Huma XXL plenum?

Probably not. Really small tank in it. You'll need a big plenum. I had a Gladius regulated, I gave up a lot of power for accuracy. Was shooting 38fpe, went down to 25fpe with a reg.

huh... well that would be dissapointing.. I got the XXL plenum which is what he says is the power maker I guess but wow I would not be happy shooting a slug @ 25 FPE I got my marauder pistol shooting a .22 @ 30 FPE lol.

Yep if you have 165cc 200bar tank you want to leave it unregulated if you want power.. Alltho that gun is ideally regulated 800fps pellet shooter. Not good platform for power.

I tell people to just yank their regulators and install a heavier hammer spring if power is most important to them.
Most of my most accurate extreme long distance guns are not regulated.

DarkRattle, head over to GTA, gatewaytoairgus.org, and pose this question to Rallyshark. He got 75fpe out of his .22 Flash pup, and is always working on something with that platform.

I did what all great airgunners who can't figure out stuff do, return the gun and buy an Air Venturi Avenger...! Thanks all

I will be putting a 25cc plenum on my .22 avenger on monday when I have some free time.(stock is 10cc). In .25 I have no doubt that you can get over 60fpe. I am pretty sure it is possible with the 22 as well. I will post some results on here soon though. I think you will like the avenger more than the flashpup aside from the crap stock. I just made my own wood stock for mine.
