I bought a 300. wsm and i need a new load for this years upcoming bear/moose hunt. Shots will could be up close to 500 yards. My neighbor and I are going to be loading together and sharing equipment. So far he has some hornady 165 and 180 grain SST. I have not kept up and bought some other heads to test out. I was thinking of some nosler 180 grain accubonds, but i am undecided. Any suggestions on bullets to try for 500 yards and closer on some big bruins or bull moose?
