I came into a large ammount of .40 s&w range brass and noted the majority had been fed to a glock. I decided, before i got started loading it, that i would buy a bulge buster and run the whole lot through it. I read on line that you attach it to a carbide factory crimp die, so i got one of those too. They arrived today, and after putting them together, im wondering what the bulge buster part even does besides attaching to the catch cup... if it works to .45 cal, the carbide ring would be the only thing touching the brass.... so the bulge buster seems to only be a thread protector for the die and a punch for the ram.... am I wrong about that? Not a big deal for $15... but just curious
