Tuning Pitbull AKC measurments (modified bulldog) with questions for tuning pros

Yes, the regulator creeps a little. Mine is only going 50 to maybe 100 psi, but enough that you need a little more hammer spring to overcome the pressure. Takes an hour or a little more to get there.



I think you should take the cap off and pull you hammer spring guide out, shorten the larger end by about half. You'll gain about 2 turns of thread engagement on the cap which is two turns stronger. 10 turns out doesn't leave a lot of engagement.

From your chart it looks like I could do a little more work and boost the power slightly while still getting 10 shots. Maybe after I see what lighter weights are doing.

You guys are doing a great job. Numbers are looking great. I find it almost just as much fun experimenting with the gun and tweaking as much as shooting it at random targets. How long are your air tubes if you don't mind me asking? Mine is flush with my PITBULL moderator as you can see.

Thanks,

Mine is roughly the same length as the stock shroud, thought I would be getting the longer one but I guess that wasn't what was in the package I bought. The extra air would be welcome, probably 2 more shots with that much more volume. But for now with 10 shots I'm good.
