Home Forums Reloading Big Game Rifles Quickload / 300 wsm, RL 26

That COAL is maybe .090 longer than average for a 300 WSM? That might be giving you some extra volume and lower pressure. My 23" and 24" 300 WSMs clock at 2975-3,000 fps with every single 180gr factory load I run through them. Those are generally right at 2.85 COAL. The loads I run longer need more powder to get there.
