[QUOTE="crkckr, post: 2029255, member: 78056"] I think starting at the beginning is the best course. First off, does fired brass fit easily back into the chamber? If not, I would suspect headspace issues. Also, in this case, neck sizing would probably be of no use to you. If it does rechamber easily, do you neck size? That is probably one of the best brass-saving measures you can use. I reload for a buddy with a Win. 22-250 where the brass does not easily rechamber. To get the brass to rechamber easily the ram on my Rockchucker has be down hard on the shell holder! Anything less and drags hard, so neck sizing is simply out of the question. Yet I am able to get many reloadings on the brass and to be honest, I'm not at all sure why! Maybe it's the Lapua brass? Although Rem brass works well, too. Generally, I neck size until the brass is a bit "draggy" to rechamber, then FL resize only enough to get the brass to go in the chamber easily. Even with supposedly brass-eating calibers like 300 RUM I can get a lot of reloads from the brass (some of the brass in my buddies .300 RUM has been reloaded 15 times! And these are test loads!). If you can use this method of sizing brass and you still get case head seperation, it very likely points to a headspace problem. If nothing else works you might try some lower pressure reloads to see if that cures the problem. I find that the data in the Lyman books usually has the lowest pressure loads. Just try perhaps 3 rounds of the lowest pressure loads you can find, forget accuracy, and try reloading the cases. If you continue to get case head seperation after 2 or 3 reloads, it becomes highly likely that it's a head space problem! The worst caliber I've experienced in this respect is .243 Win. and have had horrible luck with two different rifles in that caliber. Time for a custom barrel in the one I still have! Good luck!
