    ~~~~~~~~
    Approximately 3 psi  bar per shot. 250 bar fill. Regulator at 150 bar.

    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?

    3 Bar per shot is about what my Crown uses in .30 cal.

    My mistake. Of course it's approximately 3 bar per shot.

    The barrel is 700mm smooth-twist X.

    3 bar sounds much more correct :P

     

    Happy shooting!

    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.

    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
