I'm setting up my new Dillon 55b reloader after selling my 2 Dillon Square Deal B's. I'm using Lee carbide dies in (Station 1 Resize/Decap) , (Station 2 Powder drop and belling), (Station 3 Seat Bullet/Crimp) and station 4 is not being used. I load 9MM for my Gen3 Glock 34, 40.cal. for my Gen 2 Glock 23, 3rd gen Glock 27 and .45acp for my 3rd generation Glock 30sf. What are the pros and cons of using the standard Lee combo seating die and crimp die for seating and crimping operation? Using "Glocked" brass, Am, I better off using a dedicated crimp die in Station 4 instead of the combo seat/crimp die, or will the combo die suffice? Thanks! Wanna kill these ads? We can help!
