I agree with James. I have a .338 x .378 Wby and and wouldn't trade it for anything. But I have to load for it though. Factory ammo is right at $5 a shot. Last time I bought hulls, even they were over $2 each, so even counting on using the once fired factory brass, you're still into factory ammo at over $3 a shot, (one less loading than factory brass).
I'd go with the .338 Rum right off (~60 cents/hull), no fire forming and plenty potent out of the box. You can always sink the chamber to the Edge later if you want to. The Wby bolt face has to be a std magnum, The .378 face is larger than the rebated Rum extraction rim).
This is a case where you can't lose; either of these cartridges is Elk poison, and 1,000yd capable.
