It will fit your mag better & will give you ~ 100fps over a 7mmRM burning less powder .
Not quite up there with 7-375 or N28's in terms of speed (~100 - 150 fps) but an extremely efficient and accurate cartridge. I have all three - RM, BM & N28 - so can provide a real world side x side comp.
Ask @Kiwi Greg about 7mm BM vs other options.

Given what I want to do the 7BM is looking more and more likely, thanks for the side by side comparison
