Sizing die leaving a rub mark

[daverich4]

It turned out to be a defective die. I put my 357 setup into the press and that sizing die worked as expected. I bought a Lee sizing die which works properly as well to hold me over until I get a fix from RCBS. Thanks for all the input and suggestions.

As much as I like RCBS, I have to wonder if their quality is slipping. I just bought a set of 45acp dies and one of the seating stems had a bad burr on it.
