[QUOTE="green 788, post: 722028, member: 3781"] Try another powder, just on the off chance there's something up with that lot of Magpro. Not saying there is, but since it's driving a lot harder than you'd expect--it's possible. RL22 would be a good powder, with Nosler showing an accuracy node at 75.5 grains (work up from 71.5 grains). I'm not a fan of extreme range ladder tests personally... there's just too much that can go wrong (as you've seen, with un-repeatable results when you tried the same charge up close). Most 300 Win Mags will shoot quite well with an even 70 grains of IMR 4350, for 3000+ fps of velocity from 26" barrels. That's a max charge in some manuals, so work up from 66 grains. Dan [/QUOTE]
