Put 21 rounds of 45-70 thru my H&R this afternoon, loaded with 47 grains (By weight) 2f 777. Getting the sights readjusted. Nice tight 3 shot* groups at 200 yards, no cleaning until I went home. That just fills a Starline case to the base of an Accurate 46-405c bullet. Been running around 3 moa bench rested. Good stuff in the H&R barrel.
I would prefer real black, but the H&R has made it clear this is what it wants.
*Steel plate at 200 yards. Shoot 3 rounds, walk to the plate, paint over, walk back, adjust, shoot 3 more shots, repeat. Good exercise.
