I don't either esp since my loads were under max for what others are using with his firearms in 9major and was told changing to sc would of fixed the issue and it didn't.. only cost me 5x's the cost in supplies lmao . and also i run major in a sti edge (but .40) and never an issue with sm pistol primers. but it got to the point that after 40 rounds or so the gun would lock up from brass shavings. so who knows... now my wifes gun is using the same load with hs6 and no issues with shavings (sm rifle) in 38sc.
