7.5" Pistol key holing at 25 yards??

Try another muzzle device to rule it out. I assume that you understand how twist rate works? If so, then you should understand that the round isn't really stabilized with a 1/9 twist and a 7.5 inch barrel.

Ok, I'll swap it out and see what happens. From inspecting the barrel & CRD everything looks perfect. I'm tracking the twist on the 7.5" barrel, I just didn't expect the round to tumble to that extent @ 25yds and only a dozen or so rounds out of 190 to keyhole. I'm going to tear it apart and inspect it throughly and maybe upgrade the barrel.

I have this waiting at my FFL for me.

1/7 though. Are you sure yours is a 1/9?

Radical states it is a 1/7 twist, FYI.
