I came across and ad for a .40S&W resizing die where the brass actually passes all the way through to size out the unsupported (ie Glock) case bulge but I can't remember who makes it or what it was called.
I was interested in buying one, does anybody know anything about it?
Can only speak for the Lee. It does work . I just need to get faster with it. One thing to remember... The kit , I believe, does not include the factory crimp die. If you already have the FCD, you can try it out without the kit by simply using a appropiate sized socket extension.
