I shot a small deer and a coyote last year and the year before with this bullet in my H&R 454. the bullet nearly came apart in the coyote at 35 yards then again on the deer at 65 yards.
The coyote was walking towards me as I hit him just behind the leg in the ribs, but the bullet exited the bottom of the brisket between the front legs. FORWARD of the impact....
The deer was hit high shoulder at under 75 yards, pieces of the bullet exited... I wont call them failures, as I recovered both animals with out a problem.
'BOTH of these where the same starting load of H110 powder. The bullet shoots GREAT accuracy wise. I have switched to the Gold Dot 300g 454 bullet.
