    If the 40 cal requires an additional sizing die for reloading to eliminate a buldge at case head, why doesn't the 45?
    Thanks

    this may be answered faster in the Reloading forum, but I have no idea.

    I believe you are referring to the Factory Crimp Dies, and this was a long heated discussion many times over in the reloading forum. I have been reloading 40SW for years now and have never once used a FCD, if your sizing die is properly setup there is no need for the FCD.

    If you are talking about a bulge buster type die they are only needed when using fired brass from a Glock in a match or very, very tight chambered barrel. I have never had to use the extra die to fire previously fired Glock brass in a Glock again or in a 1911, sig or other. The one exception is if you run across brass from an early Glock before they changed the chamber support. If you run one of those cases through a die it will force a ring of brass down around the web area from the BIG bulge. That brass is not safe to load, if you look in the case you will see a crescent crack matching the unsupported part of the chamber.
