Thanks everyone for the great responses. I'll start with 3f because thats what I have. I'll work up some loads (with 3f) using the information posted here. However, next opportunity I have I'll pick some 2f and work with that. There are so many really thoughtful replies, that's why I really appreciate this group. You guys are great! I'll try to report back what happens. It might not happen until I knock down some birds, but, I'll get back to you all, for sure.
