Is your chamber saami freebore? If so def stick to 215s. N570 would be the best powder for either, RL26 works as well with 215s, 230s I'd try RL33 if you have longer freebore. 86gr H1000 pushes 215s @ 3070 fps in my rifle, rl26 goes 3160. 230s will rob a lot of powder in saami chamber and probably max around 2950.
