Elk are shot at longer ranges these days, making the shot more practice-worthy and making a shot elk tougher to find. Elk are very game animals and can go quite a ways after being shot. Anchoring an elk with a larger diameter cartridge than provides good "blood trail" makes a lot of sense. Elk have very long hair that can absorb a lot of blood and diminish a good blood trail even with complete pass-thru. My 340 Wby was built just for that purpose. It has now been used on only six elk and one caribou, except for a few whitetail on which I wanted to use it. With 50 years of hunting to my credit, I really don't see ever using it again. But it gave me great confidence when I did use it as I knew I would find my animal. When the herd scattered, and elk are herd animals, tracking my biggest bull in the aspen draw, even with snow on the ground, may have been a problem without a good blood trail. He covered 350 yards after a good shot behind the shoulder at 400 yards. The Nosler Partition bullet passed completely through him and gave us a good blood trail to follow. He was bunched up in heavy cover but the larger cartridge allowed us to find him. Not finding an animal that you know you made a good shot on is your worst nightmare, and, for the traveling hunter, an anxious memory. The resident hunter has opportunities to continue looking for the animal, but not the traveler. Good luck!
