A MESS! We just got back from an antelope hunt in Wyoming. I used the 300 ultra with the load in the title. My longest kill was only 384 yards due to the rangefinders not working properly, but at those distances I didnt get a passthrough on any of the antelope I killed! I killed my buck at 384 with a spine shattering, top of the shoulder shot. Both shoulders were jelly, but no passthru. I killed a mature doe at 350 with a double lung shot. All internal organs were nearly liquified, but still no passthru! My 3rd mature doe was at 200. I shot her because she had already been shot thru the knee joint by someone else and I didnt want her to end up as coyote food. She was trotting away at a quartering angle and I took her back at the last rib and angled up into the lungs. Still no passtrhu! All three animals were killed instantly, like they had been hit with a bolt of lightning! I think before the caribou hunt gets here Im gonna try some of the interbond bullets. I really want a passthrough shot.
