[QUOTE="cdherman, post: 2844843, member: 12282"] I think the concept of a .002 thou shoulder bump has been slower to reach the belted magnum crowd historically. I am betting Feenix was doing that for his belted mags all along. And has not had trouble. As also noted, the belt means the resizing die cannot resize as far down the case as it could with a non-belted case. Regardless if you doing a brutal max FL resize, or a shoulder bump. The die stops sizing higher due to the belt. If your belted magnum has pretty generous headspace, and if you adopt "shoulder bumping", you will likely eventually have some sticky cases. But you will not have case head separation. I managed this with my cousin's 7 RM 40 years ago. Around 3-4 firing, resizing only to bump the shoulder back a couple thou (who really knows, I was using the "soot on the case" method at the time, lacking better tools), we got sticky cases. Funny, at the time I threw out the cases that were sticky. In the meantime, I invested in Larry Willis collet reforming die, as did Feenix. And similarly, have not yet used it. [/QUOTE]
