[QUOTE="Lefty7mmstw, post: 906432, member: 48043"] Nearly every one of your charges is heavier than I'm running in my 300rum with the 225 hdy. I'm honestly thinking it's a combination of running hard and damaged brass. I don't think it's the rifle unless you've got a tight dimension you don't know about. Food for thought, hodgdon's top vel. for the 300rum with a ~ 220 grain pill is 2905 fps from a 24" bbl with retumbo. Even adding 50 fps for barrel length and 100 fps for the rl33 gets you to 3050 fps. It wouldn't be the first time I've seen bad brass mess things up; I've got a nice burn on my stw's bolt face from a box of used brass some "tool" ran too hard then sold as once fired. I tossed the brass when I had three of the twenty loose a primer in a load I had shot in the rifle about 400 times with other brass with zero issues. I had to toss 100 stw's years back working with 50cal ball powders and 7828 pushing the stw hard too; the pocket were loose, the brass would hardly chamber, and the occasional shiner/ heavy bolt lift would pop up from nowhere. Ditto on the 7rem and 375.... I've gotten tired of beating on my gear and refrain from doing so. [/QUOTE]
