I've reloaded for .45acp and I've loaded for a Kahr - but not for a .45acp Kahr. Haven't had a problem with feeding in either though, once OAL and sizing is set correctly. Have payed a little with OAL with SWC in 1911's, and seen some sensitivity when it isn't just right. The Kahr's chamber is on the tight side of spec and doesn't tolerate a sloppy crimp or sizing. It has been stated many times that Kahrs tend to be that way. With those issues settled, I have no feed problems. I find the .45acp to be one of the easiest calibers to reload.
