Home Forums Reloading Big Game Rifles N-570 in the 7mm RM and 300 WM

I haven't tried n-570 in my .300 WM. I think it may be a tad slow for that round; n-560 may be a better choice. N-560 is pretty close to RL-22/MRP, both excellent .300 WM powder choices.

N-570 is probably marginal in the 7RM even with heavy bullets, but worth a try.

I'm currently working up 26 Nosler loads; n-570 seems to have promise in that round. It's a top performer according to Q.L. It's faster than the classic 26 Nos powder, US-869, but high energy and a good performer. I think it may out perform 869 in the 26.
