what's different between these shell holders and standard ones from other manufacturers? Also what calibers are these for? I will check my local store which I think only has a few lee and rcbs products but I'll be going to the city on the 1st and I can check Sportsmans and Noslers Pro Shop.

I won't be wronged. I won't be insulted. I won't be laid a-hand on. I don't do these things to other people, and I require the same from them. John Wayne-The Shootist
