[QUOTE="Lefty7mmstw, post: 805622, member: 48043"] I think your pressure may be a bit warm if you are hitting over 3250-3300 fps with 160's in the 7rum. I ran one for a few years with 140 grain bullets doing 3500 fps and 175's doing 3100 fps. My brother has a 7 rum at present doing just shy of 3400 fps with 150 grain pills. They were/are both 26" barrels and pretty close to topped out. I was using rl25 with the 140's and I 5010 with the 175's; my brother uses retumbo with 150's. With this cal. and 160-175 grain bullets I'd really be looking at some of the powders for the 50bmg. They would get you your speed without being quite so flaky. They would also give you good case fill, which in a case like the 7rum is **** near manditory. [/QUOTE]
