RCBS 300 RUM Full Length 2-Die Set

A two die set for handloading 300 Remington Ultra Magnum. The full length sizer die brings the fired case back to SAAMI minimum dimensions, knocks out the spent primer and expands the neck to take a new bullet. Vents in the die let trapped air and excess lube escape so cases don't get dented.

The seater die has a roll crimp ring built in to seat and crimp in one stroke. Headspace is held tight so the case body length stays put during full length sizing. Uses a #38 shell holder, sold separately.
