[QUOTE="Laguna Freak, post: 2886533, member: 87188"] 74Honker is spot on. It sounds like you did not conduct any powder charge ladder tests. If I were in your shoes, I would likely back off 1.5 grains from where you hit high pressure, start seating depth at 0.060” off the lands and shoot 0.1 grain charge increments at the same PoA back up to pressure. Be sure you log PoI. You should hit pressure quite a bit lower with deeper seating. FWIW; I’ve found 30 cal Accubonds and Scirocco II of various weights from 150 to 210 grain perform better from 60 to 70 thou off lands in my Bartlein, Brux, Winchester, and Steyr barrels. [/QUOTE]
