I am loading 9mm on a LnL AP. Should I seperate the seating and crimping step which is done with one die now? As you know the press has 5 stations and I will be using a LOD so this means I will have to get the PTX expander I believe. If I seperate the seat and crimp step would it be better to get a seat die and a crimp die or can I use the combination die I have now to crimp only by backing off the seating stem and purchase only a seat die. Hope this make sense. David Wanna kill these ads? We can help!
