Yep, but remember RCBS Cowboy dies are designed (especially the dies you mention) for larger lead bullets. I have a set for my 45 Colt reloads. I understand the difference between Lee and some other dies (kinda like comparing Craftsman or Proto tools to Snap-on) and my post was in no way meant to bring up the Lee Hater BS. A Lee expander (flaring) die has always worked for me, and while I have a mixed bag of die sets (Lee, Herters, Pacific, Lyman, Redding, and RCBS) none seems to work any better than the feller behind the press handle...
