9mm accuracy issue
Hey guys, have a nagging problem. I'm working on a load for berrys 125 gr flat nose bullets in 9mm. I'm shooting out of a Springfield XD. I have previously worked up the same bullet in round nose to a very accurate round. Can't seem to figure this flat nose out. Right now I'm using 231, 4.3 gr, and am happy with that. Trying to find a good OAL. I've tried 1.055, 1.075. They cycle very well, but I can't get the groupings of the round nose. Anyone out there have success with a certain OAL? Thanks!
