Do any of you have experience with the old Pacific DL Model 100 presses? I have an accumulation of old shotshell presses and enjoy refurbishing them. The Model 100 and possibly other older Pacific presses have a crimp station (4th of six) just after the wad insertion shot drop station that I assume is for roll crimping paper hulls. The die in this station has three spacing studs on top and is spring loaded so that turning the die 1/8th turn raises or lowers the die by approx. 1/4 of an inch. I hate being dense but so far the function escapes me and I've crushed several hulls trying to figure it out. Can any of you enlighten me as to the proper way of using this crimp feature? Thanks. Gp
