I am looking for data using the 300gr barnes x in the 458 win mag. I just loaded some using 82 grains of h322 and accuracy wasn't that great. I am hoping for improvement. or is it that the 458 win mag doesn't usually like lighter bullets?

Barnes new manual recommends RL7 or H4198. Charge weights are the same with both powders. Starting- 64.0 grains for 2390 FPS and max at 69.0 grains for 2570 FPS. Hope this helps.

My Winchester 70 prefers the 500 grain bullets...but the best results I got with the little 300 grainers was using IMR-4198.
