(1st) I purchased RCBS dies, the sizing die was steel (purchased a Hornady carbide sizer). The seater was supposed to seat and crimp (didn't work), I purchased a Redding crimp die. When you add up the extras my set of 45 ACP dies turned out to be quite expensive. If I had to do it again I wouldn't purchase RCBS dies for my 45 ACP 1911, apparently I discarded the steel sizing die, no date on the other dies, best guess 15 years old + or -. FWIW I would suggest a separate crimp die, do not try to crimp and seat a bullet in the same operation.. William
