Confused About Bullet Performance

[longrange700]

can't speech of the gamekings but while looking for a hunting bullet for my 308. I settled on the 178 a-max because of how many good reviews I read on here about it. So far this year this bullet has done awesome on everything shot with it. My wife shot a large bodied 3x5 bull elk at 185 yards bullet entered midbody tight to the shoulder and excited through the muscle on the opposite side leg leaving about a 1'' hole and lots of messed up muscle and bone it hit a rib going in and performed great,she also shot a 4x4 whitetail at 415 yards downhill the bullet entered midbody tight to the shoulder and left a 1'' exit hole not very much bloodshot, the deer humped up at the shot and tipped over 15 seconds later he never took a step, the elk made it about 30 feet before going down. I have shot three coyotes at 100,250,575 and all three were drt with huge exit wounds. I am not sure if its just the bullet or what but I have never heard a smack so loud when it hits an animal the buck sounded like she shot a rock it was so loud. My gun is throwing the 178s at 2740 out of a 26 inch tube and shoots 1/2 inch at a 100 and gets better the farther out you go.
