I usally shoot an H&G 68 style 200 gr LSWC out of my kimber. I have switched over to plated b/c the wife got pregnat and is all concerned about lead issues. Lead issuses aside, I have been having real trouble making them fuction.
Then the light bulb came on when i read a post by 243winxb.
That's the key. Berry's 200 gr swc are not H&G 68 style. they are about .030 shorter in oal. So if i seat them at 1.250 like there lead counterpart it makes the shoulder higher causing problems. I should have used my barrel as a gauge and i would have found this out sooner. I seated them at 1.240 and problem solved. I was trying crimp, flare, all kinds of stuff with no results. Live and learn.

my gold cup likes the measurement from the head to the shoulder of the swc to be .947" The reason to measure from these 2 points is that the alloy of the cast bullet changes the length of the bullet from base to tip of the bullet. As i seat the bullet into the rifling to eliminate end play, this measurement must remain constant. A change as little as .005" longer will keep the slide from fully closing. This is how i load to get accuracy at 50 yds. for bullseye competitions.
