[QUOTE="Lefty7mmstw, post: 1207941, member: 48043"] Switch to a double base powder. h4831 and h1000 are both single base and yield about the same energy per grain and it is less than a similar speed double base powder. I would try rl26 if I were you... I have burned more rl22 and rl25 in big 7''mms than anything else, but if I were to start today it would be rl26. About the only other powder I will burn in a big 7mm is retumbo- my 7rum likes that powder with 175-180's ( when I finish torching that pipe I'll try to get the next barrel on rl powder though)... Rl 26 produces very good velocity in 7mm and is pretty temp stable, not to mention it has de-coppering agent. [/QUOTE]
