I like Accubonds a lot, but couldn't get them to shoot well out of my son's 6.5 Creed. 129 SST's shot 1/2 MOA consistently behind a max charge of W760, so that's what he used this fall. 2 mature mulies, 2 antelope, 1 mature bull elk and a 380 lb black bear later, I'm convinced that this load is suited just fine for Western hunting, including elk. The only animal that required a 2nd shot was one of the antelope oddly enough.
My other CM only likes 122gr ammo. I won't use it for Moose.. but a punctured lung is a punctured lung.
Either way, anything through the lungs is deadly.
