Im shooting Extreme plated 200gr swc in a G41, over 5.1 gr of Shooters World CLEAN SHOT. I first seated at 1.230 and I wasnt crimping, they continued too 3 point, even with different mags. I opened it up all the way to 1.270, still fit great in magazines, and the problem all but went away. Put just a slight touch of a crimp... Butter! Oh, I also found that polishing the ramp and throat, ESPECIALLY ON THE SIDES helps tremendously.
