Congratulations! I purchased one last week too. Im shooting it for the first time this weekend. I am new to ML but between what people have been kindly enough to say here and things I have ready on line they shoot Pyrodex pellets and Powerbelt .295 grain well. I Have been asking the same question and did a little research. Thats what came up he most. Ill let you know how they work when I go out. Good luck!
