Most of the guys we hunt Moose with all use FailSafe factory Ammo or Barnes-X Weatherby Ammo. I agree with Colo Wolf on the velocity issue, most of the tests show less then advertised velocity for the FailSafes, but the retained weight is definitly accurate. I have removed 300 and 338 caliber bullets that went right thru ribs on one side and lodged in a rib or skin on the other and the bullet is all there with the petals bent back.

Its one of our favorites.
