RCBS 1776 Features The RCBS 1776 Full-Length Sizer Die brings .308 Win cases to SAAMI minimum cartridge dimensions sizing the outside of the case while de-priming and expanding the neck to accept a new bullet. Built-in vents prevent case damage caused by trapped air or excessive lubricant during the sizing stroke a detail that keeps cases from being dented or deformed. Headspace is held to minimum tolerances preventing changes to case body length that can occur with less precise full-length sizing dies. The included Seater Die features a built-in roll crimper securing the bullet in place at the same moment it is seated for a consistent SAAMI-correct finished round. Both dies use the standard 7/8-14 thread pattern making them compatible with virtually every reloading press on the market. Proprietary RCBS die steel ensures long service life even under high-volume reloading sessions. What sets this commemorative set apart is its presentation: each die set ships in a custom wooden box featuring special 250th anniversary graphics while the dies themselves remain packaged in their conventional plastic die box inside. This lets reloaders use the plastic box for everyday die storage while keeping the wooden box on hand for bullets tools or display making the RCBS 1776 a functional die set and a collectible piece in one.
