You said "... loading .45 caliber rounds." I understood you to mean .45 Colt, but after reading Anyrange's post, he thought you meant .45 ACP. Which is it?
What do you mean by, "The dies only come with correct 45 ACP tapper."?
Also, what did you mean by, "Use the normal seating die for crimp ..."? Does the Redding come with a taper crimper? I have some Redding dies, but not in .45 ACP.
BTW, I love the Redding dies with the competition seater, for rifle. But for my .45 ACP, I like the Dillon for its ease of partial disassembly for cleaning without affecting adjustments.
