I shot some Doubletap 300gr. Sierra HPBT match last weekend. It was right at 2800 fps. and yielded a 5/8" 4-shot group at 100 yards. My reloads were another issue all together. I think that I had the bullets seated out too far. I realize that this gun needs to be shot at 300 plus yards, but I just didn't have time to take it to the longer range. I will soon, however.
