I have shot several groups with mine and have had really good accuracy but have only gotten about 2950-3000 fps out of it. I shoot the 225 Accubond out of mine at 2625 fps and I am currently on a hunt in canada with it. My buddy shoots them out of his .338 federal and he says that they smack deer at about 2800 fps. I will keep working with it and see when I get home. My gun shoots 1/2" with th AB's so I am not anxious to change.
