It was at 80 yards and the cow elk was the biggest I have ever seen. We estimated her on the hoof at over 900 pounds. I got 375 pounds of deboned meat from that cow. She walked about thirty yards after the shot and fell over. Never broke into a run, at first I thought I missed as I had been having problems with the rifle getting good groups and CVA said the powder was so bad that it would not upset the bullet into the rifleing which was the reason for the keyholeing on some shots. That convince me that you do not need 150gr. of Tripple Seven to kill and elk. Heavy bullets rock!!! By the way it was with a T/C Scout and my first elk. Sorry I sold the Scout to buy my Omega. Now I wish I had kept the Scout as the Omega is becoming less and less popular with me. I am now doing White rifles as I can find them. Have a 91 in .504 and am working on getting a Thunderbolt in .504 also. Have any to sell??
