[QUOTE="Lefty7mmstw, post: 1076508, member: 48043"] just worked up the 140 nos bt in my 7stw today with rl26 using rp brass and a 215. I've got a 10" twist 24" bbl.... At 80 grains I was at 3286 fps.... at 82 grains I was at 3395 fps... at 84 grains I was at 3485 fps... I got a bit of a shiner at 84 grains but no brass flow... best accuracy was at 80 and 84 grains but no load was bad I suspect a good working load to be found in the 81 to 83 grain range... In contrast, 82 rl25 with the same bullet, primer, case yields 3200 fps with similar accuracy... [/QUOTE]
