RCBS offers this two-die full-length reloading set for 7mm Remington Ultra Magnum, designed specifically for bottleneck case reloading. The set includes a Full-Length Sizer Die with Expander-Decapping Unit and a Seater Die with Bullet Seater Plug.
The Full-Length Sizer Die sizes the case to SAAMI minimum cartridge dimensions, working the outside of the case while de-priming and expanding the neck to accept the bullet. Venting in the die prevents case damage from trapped air and excessive lubricant, while headspace is maintained at minimum tolerances to preserve case body length during sizing.
The included Seater Die features a built-in roll crimper that secures the bullet during the seating process. This two-die set measures 1.60 x 4.50 x 6.00 inches and is engineered for full-length reloading of 7mm Remington Ultra Magnum cartridges.
