Ridge Runner... Use WC872 in the 300 RUM. I agree, very cheap (which is nice in those big cases) and practically can't overcharge.
Fill up the case, whipe 'er off and seat the bullet. Not too many powders can you do that with.

Killed a nice 6X bull in Colorado and a 18" 8 point in PA in 2004 using that powder. It didn't seem to vary too much in the 10,000 of elevation change either. I haven't tried in the 7 RUM yet...I guess b/c I found a good load using RETUMBO...I had just stopped. Now that I'm fiddling around again I may try it out.

Check out Catfish's thread and I've posted results from the Bergers.
