[QUOTE="Veteran, post: 2844780, member: 118038"] Nope, this is a common problem with belted magnum cases. I had the same issues on my .300 WM. Advice I got here was to bump the brass shoulder down .002 each time I reload them. What's happening is you are over compressing the whole case down onto that belt each time, and then when it is fired, it stretches it back out right at above the belt. It will metal fatique there in 3 firings or so, and you will have case head separation. Bump only the shoulder down and set the die not to press the whole case body down onto that belt. You can also of course neck load your belted magnums, but many here and Eric Cortina believe that is not as accurate as full case resizing. So, you do full case resizing but only to the extent, your shoulder bumps down .002 each re sizing. [/QUOTE]
