Hmmm. I was afraid that might be the case. As I reported in Post #17 above, RCBS confirmed that there is no difference in the sizing die between their Standard and Cowboy die sets. The differences are only in the expander and seater dies, and the only difference in the expander is the expanding plug diameter and the fact that it comes with two expanding plugs.It is a fact that my Lee sizer is larger than my RCBS Cowboy, but that could be just my good fortune.
