I have not yet shot the rifle to less than 170 bar. I find the tune to be air efficient for 70+ fpe.

I don't have any targets to post, as I haven't taken this rifle to the range in 3 weeks due to the weather here in north-central Alabama. It's either too cold or its wet.
On the range at 50 and 100 yards this rifle was sub-MOA.

3 psi drop per shot huh? You sure you did the math? With a 250 bar fill coming down to 170 bar is 1160 psi..at 3 psi per shot that means you get 386 shots...at what power is that? Maybe you meant 30?

970 with the 33g JSB from a .25? what on earth did he do to it? and is this a 600 or 700mm barrel?

That information might be proprietary.
Seriously though , "The Master" does market a power tune kit, if I'm not mistaken.
The suspect in question:
Note in the photos the modification to produce increased plenum space.

*Addendum: As the photo clearly shows, the rifle does not appear to be the vaunted X version Impact.
Dispensation, please. I'm getting old.

3 bar sounds much more correct
Happy shooting!

Honestly with fox going to a 3yr warranty I would really like to have an impact. But I just bought my r5m, and can wait to see if they make any changes to the impact with all the new stuff coming out.

If i'm doing this right this are the number of shots he is getting 250bar-150 reg set =100 bar /3 bar=> 33 shots
reg set @170 = 26 shots

Very impressive results. What would you say your valve is set at? What line is it on?
hope I can achieve similar results.
Thanks for posting.
