Catfish, I'll have to respectfully dissagree on the head spacing issue. Yes, rimmed cases can head space on the rim, BUT, they shouldn't. Especially in a Contender or Encore, bottleneck cases should be sized to head space on the shoulder, not the rim. If not, you're just asking for miss-fires, poor accuracy, short case life, etc...The advantage to rimmed cases is that they work much better with the extractor. Just my opinion, but I think it's shared by many who know a lot more than me. I suffered through a lot of tough lessons many years ago with my first .
