Best powder for .338RUM and Heavy bullets?

I found that Retumbo works best with the 300 grain match king at 94grains 2765fps.
RL25 with 225 at 98 grains 3240fps.
RL 22 with 210 ttsx's at 97.5 grains 3390fps.

Dont use the Matchking on game at closer than 500yards. bad idea.

The 225 or 250 AB will do well from point blank to your 700-800 yards. So will the Barnes ttsx's from 185-225 grains.

Thanks for the info. I think I'll try and work up a load with the 250 NAB. Thanks for the advice on matchkings. I think I'm just a likely to get a shot an an Elk at 150yrds as I am at 500yrds. I'm a little worried about the MK having problems at close range high velocity.
