[QUOTE="Lefty7mmstw, post: 992460, member: 48043"] Muddy, I've pushed the 50 cal powders to their limits in the 7stw and netted 3550-3600 fps with 140's, but at pressures that would kill brass in a few firings. 3400 fps is a sane top vel. in a 26" bbl. with a 140... even if you ad 200 fps for an extra 4" of bbl. (not gonna happen but I'll give him the benefit of the doubt) you still fall in the 3600 fps range... ad 100 fpr for the slow twist and the extra couple of grains of powder you will need to get to pressure( it is really more of a net sum than a gain but again- the benefit of the doubt) and you [B][I][U]MAY[/U][/I][/B] have a chance of getting close to 3700 fps with the right combo... As to 120's, the only time I've seen 4000 fps with a 7mm 120 is using 50 cal ball offerings with a 7rum and then only barely. [/QUOTE]
