It may be a novice question but I have the Lee deluxe 4 die set(.45 Colt) with the factory crimp die. My question is which die can/should I use to crimp bullets that have no cannelure, or can they not be crimped at all. Should I use the factory crimp die or the bullet seating die adjusted in deeper to add a crimp. I have been loading for a few years now but this one has me stumped. Thanks for the replies in advance.
