With high efficiency brakes, recoil is not bad at all, my .338 NM burning 88 grains of H1000 under a 300 Berger going 2700 from a 24" tube isn't bad at all, about like a 10 lb unbraked .308 win. Here is a video showi g that it isn't bad at all, as long as you have a good brake. I shot my fathers 9 lb AR-10 right after this, and recoil was very similar. This is with a MBM Beast 5 port. Barrel contour is a #5, and I'm using a March 2.5-25. It's not an edge, but in my friends 28" 338 nm, they are going 2830 with the same charge, not terribly far behind what an edge would be doing.
