Either should do great. Today I ordered some loaded Hornady 58gr ammo today. Been using the win supreme 55bst's, they shoot itty bitty groups, are really flat shooting and the nickel cases feed really slick and reliable like, in the semi auto. I'm thinking that the vmax will exit less than the nosler 55's. I milled a couple noslers and vmax's in half to compare jackets/cores/etc, and found a considerable difference in the two. Have only shot one coyote with the 55 nosler bst, initially I thought it didn't exit, but later found a nickel sized exit hole (which for a 243 isn't bad, but it would be nifty to have no hole if possible). The nosler is solid copper for about a 1/4 of it's length at the base.
