Before I knew that the .270 wasn't enough gun for moose I took one just about every year for 20 years using over the counter 140 and 150 grain ammo. Usually federal blue box or remington core lokt. Never lost an animal and shots were anywhere from 50 to 300 yards, most at around 250 since that's the average distance across the slough we usually hunt on.
You don't get many complete pass throughs on a moose with a .270 but I did recover a good portion of the bullets stuck to the opposite hide.
