The RCBS X Die Full Length Die Set (RCBS part no. 37712) gives .30-06 Springfield handloaders an excellent choice for reloading that all but eliminates repeat case trimming. What makes this die set special is a mandrel that, after a single initial trim of 0.02 inches off maximum case length, keeps future case growth in check so trimming again is rarely necessary. During sizing, the mandrel contacts the case mouth in a way that cuts down growth rate, and because of the extremely close tolerance between the mandrel and neck wall, the neck does not thicken as the case is pushed back the way it can with a conventional expander ball. Built by RCBS, this Full Length set resizes the entire .30-06 Springfield case body to factory-spec dimensions for reliable chambering.

Frequently Asked Questions

What makes the X Die different from a standard full-length die? Its mandrel controls case growth during sizing, so cases rarely need trimming again after the initial trim.

Does this thicken the case neck over repeated firings? No, the extremely close mandrel-to-neck tolerance prevents the neck wall from thickening as the case is pushed back.
