[QUOTE="Kevin Thomas, post: 441054, member: 15748"] Hi George, Sounds to me like a combination of a relatively mild load, and a bit of a headspace issue. May be that neither is a real problem, but you're seeing indications of both here. If the primers backing out like this, then there isn't enough pressure to cause the case to stretch to fill the gap that amounts to headspace. That's why you're seeing protruding primers, rather than flattened primers. The 4350 is a great powder for most of the magnums, but it is a bit on the fast side when compared to some of the newer powders and the more recent cartridges. Truly a great powder in 300 Win Mag, probably a bit too fast for optimum performance in a RUM. Several others have mentioned some options here that would be worth a try. On the second issue, reloading manuals should be treated as a simple report saying "we tried this combination, and these are the results we got." This is why you see the various differences you do from one manual to the next. None are "wrong" (at least that I've ever seen), but they are different. As they say, your milage may vary. [/QUOTE]
