Re: 300 WSM reloading info request
I have found that with 150-165 grain bullets that powders in the burn rate close to H4350, RL-17, and RL-19 work best. When I move up to 180-190 weight I have had very good results with N165 and IMR-7828.
Here are a couple of targets that were shot with my Winchester Model 70 Coyote. It is a stock gun with a Timny trigger.
First one was shot with 155 Sierra Match bullets, RL-19 powder in Norma cases. It is a five shot group at 100 yards.The second one was shot with 185 Berger Hybrids, and IMR-7828. It is a 3 shot group at 100 yards.
