If this cartridge could get a 60gr nosler out the muzzle above 3300 I'd be all over it, but all the load data that I've seen lists around 3100 max, which I can already do with .223 at 5.56 pressures.
Don't believe the books or BS. The lawyers have those books watered down. 80s will do 3000 out of a 24" barrel. 55s will do 3400 and 60s 3350. Try stick powders between H322 and H4895 You should top out around 27-27.5gr.

The 6.8 is the best choice for hunting deer and hogs with an AR15.
