Lee Gunsmith And Reloading Equipment. Three dies that ensure perfect alignment and concentricity as well as a roll cut wad base ensure a consistently tight neck. These dies work with most reloading presses with standard threads. The only difference between the Pacesetter and the non-progressive styles is that the non-progressive styles have a crimp groove. The non-progressive style has a crimp groove that is too small to be useful. The larger size of the non-progressive styles is that the crimp groove is at the bottom of the die and not in the middle. With larger case calibers there is less chance for slippage.
