My rifle has harvested 4 whitetail and 1 hog so far this season. 140 H Vlds at 3170fps. Distances were 200,378,550,580,720. The 200 had a 2" exit hole. The 378-580 had a 3/4-1" exit. Then the 100lb hog at 720 was shot through the heart and on the exit side you could see where the bullet was protruding out of the muscle but didn't make it past the hide probably due to the thick cartilaged shoulders of hogs. I think it would do well on elk at closer ranges, but I would prefer a 338
