I've always used Speers and Hornadys in several cartridges. Both bullets seem to shoot well consistently. As southtexas said, "terminal perfomrance is indistinguishable." I have found that the .284" 154gr Hornady and the .308" 165grn Hot-Cor act more like a premium bullet than a cup and core generic.

This is God's universe, and he has a plan. You might think that you have aa better plan, but you don't have a universe.
