Killed a bull Elk with the 168gr from a 280 AI last week..409 yards uphill bullet clipped the edge of the scapula going in made about an inch and a half bloodshot entrance hole, made an inch hole thru both lungs and did not exit..I really didn't look much for the bullet it was getting late and we needed to get the meat packed out...at the shot the bull lunged up on it's rear legs then walked about 30 yards and fell over dead !
