I've still got 200-300 rds. of the original CCI Lawman 200 gr. "flying ashtray" rounds. I bought a bunch of them, after verifying they cycled, without problems, through the '70 series Mark IV Gov't Model I was using at the time.
I shot them along with several other brands, and there's no question the CCI 200 gr. always gave a sharper, quicker recoil than the other rds. I used.
Big hole in the tip of that bullet. They were also loading the same bullet in CCI's Blazers, back in the late '80s, I think it was.
