[QUOTE="Mike6158, post: 341808, member: 1039"] I'll give you a dollar for all of your 215M primers :cool: 3400 fps? Man... those are humming... no signs of pressure problems? I don't have any specific advice but I can say that I've had good luck in my 7mm Rem Mag (not SM) with 4831SC and RE15 (about to test H1000). The best groups (by a visible margin at 300 yards) were with RE-15. I've also had real good luck with ladder testing a range of velocities rather than load the fastest I can get. I'm not saying fastest is bad, just that sometimes it's not the most accurate. I ladder tested some rounds for a .308 recently and the max velocity (by the book) was the second best group. The best group was 100 fps slower than the max charge / velocity recommended in the Sierra manual. Actually... about 150 fps slower judging drop against the results from LoadBase (that's the last time I test rounds without a chronograph, too many questions come from not knowing the velocity of the round I'm testing) [/QUOTE]
