Shot a mature bull bison last week with the 300 grain TSX's. Range was approximately 85 yards. Load was 51 grains of IMR 3031. Estimated muzzle velocity was 2,100 fps.
Bison was hit a total of 6 times. 2 bullets passed through, 3 were recovered (2 on the off side just under the hide) and 1 could not be found. Massive damage to the lungs and surrounding rib bones on both sides.
Two bullets looked like a poster child for Barnes advertisements with a perfect 4 petal fold back and they weighed 300 grains. The other bullet recovered had 1 petal broken off.
