This Oct. I shot a big bull elk thru both shoulders at 60 yards with a 140XLC out of my 7mm-08. The bullet slammed thru the shoulders and left a quater sized exit hole. After shooting a whitetail buck end to end and getting the same results Ive come to the conclusion that these bullets are not designed for thin skinned and small boned animals such as deer. The elk dropped where he stood and the buck ran about 70 yards and required a second shot, didnt bleed all the much either.
