Gonna try to copy a 175 fed gm first.I'm still debating with neck or full size.I was about to pull the trigger on dillon 3 set die set for 65.00.Now I'm reading you dont have to crimp at all?What would I do with the crimp die?The guy at the dillon dealer said if I get a case stuck its alot easier to remove on the dillon dies.Do they get get stuck often?Can you use a comp die on a 550?Should I just buy a sizing/deprime and seating die separate and not bother with a crimp die?It's for my bolt gun only.
