BTW, I don't use North Fork in the .338WM, I use 225g AccuBonds with 225g SST as my practice loads. I've only taken two elk with it but it does make noticeably bigger holes than the 7mm RM and so far all bullets have exited. The last elk I killed with it was in 2013 at 487 yards and bullet placement was very similar to where I think I hit the cow with the 7mm RM last year - a few inches under the spine and a little further back than I wanted. The difference is the cow shot with the .338WM, or what is left of her, is in my freezer.
If a bigger faster bullet is the answer to poor shot placement you might want to look into a 50BMG....
