I can tell you this, if you do shoot larger bullets DONT TELL CVA's CS. They flat out told me if i used any type or amount of 3FG powder it would void the warranty. Two different reps told me this and they offered no reason why even though 3 pellets makes more peak pressure.

Thats kinda funny because Hodgdon does NOT recommend any 3 pellet load but they do have Triple7 3FG and Pyro P load data for 50cals.
