I'm setting my press up to load 10mm for the 1st time. Anybody else had this problem? I'm using RCBS dies and the seater seems to be seating the bullet on the shoulder of the bullet and gouging the crap of it. So far I've tried 180gr Precision Deltas and 180gr Xtreme plated bullets with the same gouging outcome. Thinking of maybe sanding the seater plug down a little, so that it seats the bullet with the FP of the bullet instead of gouging the shoulder. I load 40S&W with Lee dies and do not have this problem. I posted this in the 10mm reloading section also. I actually just discovered that part of the forum 2 days ago. lol -Wade- Wanna kill these ads? We can help!
