I've just started handloading for 300 Blackout and have been only using W296 (same as H110) with 125 gr., 130 gr., and 150 gr. projectiles. Have not had a chance to chronograph any loads yet so I've been loading on the conservative side. When using an almost equivalent charge of powder in .357 Mag I think some manuals recommend a magnum small pistol primer ( I always thought because some ball powders are a little harder to ignite). But I don't think I saw any manuals that use other than standard small rifle primers in 300 Blackout.
Has anyone here used Small magnum rifle primers with W296 in 300 Blackout?
