glassblower Posted January 31, 2014 Share Posted January 31, 2014 Which 40 cal Bullet seating die are people using with 180 Xtreme RNFP? I use a Redding Competition seating die for seating mostly 40 cal MG 180 JHp's with very little variation in OAL. When I load Xtreme 180 RNFP the OAL variation exceeded my comfort levels (0.03 to either side). There is not enough variation in the Xtreme bullets themselves to account for the variation. I noticed the Redding die does not fit the Xtreme bullet profile as well as it does the MG, so my thought is that there are other dies more suitable for the Xtremes. FWIW, I use a Redding seating die to seat 9mm Xtreme 124 RN with very little OAL variation. Thanks, Al Quote Link to comment Share on other sites More sharing options...
