Reading the .300WSM load thread, someone mentioned grabbing some Hornady Superformance. I had no clue that they now offered a .300 WSM round. For the longest time, they refused to load a .300WSM because of their participation in the .300 RCM design process. Wondering if anyone has any first hand experience on game with the GMX bullets. It's the only thing they are offering in a WSM right now other than the 200 Gr which is slower than I like to shoot. I've shot their SST, BTSPs and SPs over the years and like all three in the right applications. Tell me about the GMX performance on live animals.
