John that's was back in the 80's, and really don't remember. But when shooting them and them grouping like they were I said to myself why even bother. I sold my gauge and never checked them again. I use Redding bushing neck die, body die when the shoulder needs bumped back and Forester seating die. Beside my benchrest guns I have many custom sporter, varmint, and long range guns that shoot bug holes. Greg
