Well I never shot an elk with them but I did kill two moose with them up in Newfoundland, my primary rifle got damaged in transit, so I used a 270 with said bullet. Elk is not going to be a problem, or anything else you have a mind to shoot with a 270 for that matter. Here is what you do, work up a load then go shoot a dozen elk over the next 10 or so years. Then decide if it works or not. Elk are made of Skin hair, meat and bone, not Chobham Armor.
