[QUOTE="Lefty7mmstw, post: 1020362, member: 48043"] Mudrunner2005 will likely say 7828sc with a 168-180 grain pill... I'll give my .02 also... I've been using 82 rl25 with a 140 nos ab for two rifles now; the last rifle was about 3400 fps with rl25 and the 140ab... the new rifle hasn't been over a chrono I trust yet. My pops is running the 140 sierra pro hunter with enough rl22 to pass 3300 fps by a good bit. If you don't work the heck out of your rifle it will last a lot better than if you squeeze it for the last few fps of course, so we don't push much over 60 kpsi with our rifles. The 7stw will not show brass distress (shiners on the head/ loose pockets) until well over 70 kpsi so watch for heavier bolt lift first. The shoe test is appropriate here; if you couldn't open the bolt with a tap from your shoe, the load is too hot. Logical max speeds for an stw are roughly 3600 fps for a 120, 3400 fps for a 140, and 3050 fps for a 175-180. [/QUOTE]
