Approach max loads with caution can get pressure spikes real quick. Especially as the ambient temperatures start to climb. But can get good velocities out of it in 300 mag. You know I think I heard this before and thinking thats why I never used the powder due to it was effected by high temps like we have in AZ. I dont load max loads or even close but the pressure spike in high temps would bother me. Thanks for the memory Jog and heads up. Share this post Link to post Share on other sites
