This is the before and after of a .264 130 gr Accubond that left the muzzle of a 264 Win mag at 3350 fps average after it struck a deer at 111 yards on the edge of the front shoulder and then traveled the full length of the deer and was found in the ham. Recovered weight is 87 grs. That comes out to about 60% weight retention. It did what is was supposed to do.
