[QUOTE="uncleB, post: 96854, member: 4679"] JKO, since there has not been too much response I will throw in my 2cents the only vv powder you mentioned that I have tried is N170 it is a very slow burn rate powder, too slow for my 338 Lapua Mag Imp.(it likes RL25). since a 30-416 Rigby is wildly overbore N170 might be a good place to start but dont try too many powders as your throat life will be very short. dont even try H1000 it is way too fast if you want to try Hodgdon start at Retumbo and work to H50bmg . I have heard that 20N29 works well in this application but have never talked to anyone that has shot 24N42 [/QUOTE]
