I saw someone say .270 I agree with that look at the balistic chart it has almost the same drop and engary as a 30-06 and a 7mm out to 500 yards without the recoil. I have used mine on elk and would not even slow down to take it on a moose hunt. If you are looking for something different I would go with a 25-06 remington. I got one last chritmas and love it. It has less recoil then .270win and is great engery out to 400 yards on Coues, Mule deer and some even say Elk. I drew a Mule deer tag this year and took my med. sized Muley ant almost 200 with a 117 gr hornady sst with one shot. I even went out and got a 25-06 for my daughter to start hunting with. And how trys a shoot over 400 yards anyway.
