H 4895 has been my go-to powder for many years in the 8x57. The one I shoot most is an 8x57 Ackley that has a very bad attitude when it comes to putting down deer and elk. I just built a 8mm on the 7mm Mashburn Super case on a pre 64 M 70 but then had to have major shoulder reconstruction so can't shoot it. Anyone else ever play with that wildcat? If so, any load data?
