No muzzle brake, huh? That otta be thumpin' ya pretty fair

Me thinks I'm a wimp.
Good data. Appreciate it. Thus, I'll procede with the takeoff bbl should the fella in CO. decide to let it go. I think its the 26" blue sporter bbl, not the heavy one.

A good thing is that the brake could be swapped from my current bbl. Saves a bit of the 160 that it took to get it installed on this bbl.
Have you tried any of that 7828 SSC powder yet? I seem to have to squeeze the last bit of velocity out of stuff.
Those velocities are only 150 fps slower that my spec. but I doubt that any animal would know the difference......
