There are a variety of powders that work well for both. Reloder 15, Varget, 4895, TAC/2460, 2520, WC844 and WC846 just to name a few. I am personally more into ball powders these days because they are cheaper and easier to work with. The more I shoot the bigger difference that makes. If I were just buying a pound of powder here and there it might be a different story.
New gun, same ol' shot.
