I run 165 Interbonds over IMR4895 @ 2750, from a 20" Sako .308. Took a bull moose at 290 yards last fall, and it died a fairly quick death. You don't need super speed to kill, just put the bullet where it belongs, and the freezer will be full.
180 SST's run about 2610 in this 20" barrel, and brass lasts 20+ firings.
