[QUOTE="Lefty7mmstw, post: 1067386, member: 48043"] Remember that [I][B]you do not have to reach full pressure to get a good load[/B][/I]. The saum's and wsm's are topping at 65kpsi, but you can run them in the high 50's just fine. Hell, I'm using 69.5 grains wc872 in my 270win with a 130 bonded as that's the only powder that shoots with the bullet. It's just south of 2700 fps with a 130, but she'll toss ten in an inch at 100 as fast as I can rack the bolt. I doubt I'm over 50Kpsi with the combo. I'd simply start at the recommended start for a slightly faster powder and work up slowly 'till you either start seeing pressure signs or run out of case capacity. She ought to be very accurate with a mild load and a stick single base. I've always loved I5010 for this, but that powder is hard to find now. I'd use a mag. primer and possibly even jamb the bullet to help with start pressures if she seems a bit mild when you run out of capacity. [/QUOTE]
