[QUOTE="Lefty7mmstw, post: 1115463, member: 48043"] harleybug, the last time out my 5 shot string was 2932 fps ( 19 fps x variation) with my 7stw and Berger 195's. That load is 2 grains down from the top safe load I have loaded; even that load was showing zero brass distress and would have been over 3,000 fps. I just don't run my rifles hard so I'll eat the 80-100 fps and settle where I'm at for now. Who knows, I may break out the rl50 and get another 100 fps at the same pressure. Lord knows I have plenty of case capacity... The reason I've been using rl33 is I have 10 pounds of it and I wasn't burning much. I actually bought a couple of pounds of rl26 for the rifle but I'll likely use that powder in my 300win. rl26 is bit too dense and fast for the 7stw with heavies. I'll be taking the rifle as far out as I can tomorrow for some long distance testing; I've got a few spots west of here that I can shoot 1/4 mile when it's windy and past 1,000 yards if it's not too bad. Who knows, I may take my 7rum out too with 180 sierra's pushed by retumbo and see which one eats the other's dust. [/QUOTE]
