I loaded a few rounds for my Kimber Stainless II in 45 acp a while back in my Wilson 47D Mags and I believe, maybe I didn't have quite enough taper crimp from my LEE 4 Die set. the rounds seemed to not be coming up the magazine far enough to allow them to be pushed into the chamber. Then I read the directions for the mags and it said for taper crimp about .468" and 1.240-1.250" fol COL would perform the best for hand loads. Does .468" sound reasonable? They seemed to feed alright when crimped to that spec. and seemed to pass the plunk test when dropped into the barrel. Anyone else need a little more crimp when using these mags? I made sure to check the COAL of the rounds to make sure that wasn't the reason the rounds were failing to rise up far enough in the mags. Thanks for all input! 
But if I have any more problems I'll give it a try Thanks!
