I shot a small yearling tonight for crop damage with a 51 absolute hammer out of my 1-12 twist 22-250. Muzzle velocity is 4090 fps I shot this one at 194 yards so impact velocity was 3325 fps according to my calculator.
The shot was quartering towards and I hit a touch behind the shoulder and it exited about the next to last rib. Slightly larger than caliber entrance and quarter sized exit hole. The usual shredded internals. I did find a petal on the inside of the ribs on the off side.
This is a successful test of a hammer at marginal stability according to the site so I can't recommend this bullet 100% in a 12 twist on game but I did work once. I'd like to see this test repeated a few times to confirm proper performance in my rifle.
