[QUOTE="highdrum, post: 1932780, member: 13732"] You're going to be best off with Retumbo, IMR8133, RL33, N570, H50BMG. That's an 86gr capacity case and a small bore size, slower will be your friend unless you want a poor case fill %. I just ordered an 8 twist barrel myself. Either going to do a 257 wby or Miles' new 25-7 blaser, it has 84gr capacity 30° shoulder 0.320" neck and will be around 3.34" coal. [/QUOTE]
