Black Hills Ammunition just got back to me, out of a 16" barrel, their 5.56 62gr TSX has ~916 ft/lbs at 100 yards.  Plus I'll have a suppressor that should (theoretically) boost that number slightly.  Same ammo out of a 20" should have 983 ft/lbs. at 100.

Ok, good.  Still no problem meeting Game and Parks minimum (Anything from 62-79gr will work).  Let us know after you've had a chance to test it.

Was there a velocity specified or did I miss that? I am about to work up a load with this 62gr TSX and I am shooting for 3000 fps which is a max load with TAC
