My only experience has been with the 335 grain .500 diameter that I use in a 500 Mag. I loaded them as if they were jacketed, admitted I was not at the maximum by any means, but had no issues at all.

A fellow shooter said he didn't like them because they were made for the 50 AE and had no cannelure thus had nowhere to crimp. I set them to the proper OAL and crimped without a cannelure, had no issues of backing out under recoil or such.
