Redding Reloading Equipment 7mm Remington Magnum Rifle Competition Bushing Neck Sizing Die

The design concept is similar to our competition seating die, where the cartridge case is fully supported and aligned with the sizing bushing before the sizing process commences. During the sizing process, the cartridge case remains supported within the tightly chambered sliding sleeve as it moves upward, while the resizing bushing self-centers on the case neck. The decapping rod is precisely aligned by utilizing the internal components of the die as a linear support, akin to a firing pin. The micrometer adjustment provides precise control over the desired amount of neck length to be sized. This die is intended for use by competition shooters who have meticulously prepared their cartridge cases and prefer not to use a sizing button. The device incorporates an internal sliding sleeve that supports and aligns the cartridge case with the neck sizing bushing prior to the commencement of the sizing process Interchangeable bushings enable precise selection of the appropriate neck sizing for specific requirements The micrometer adjustable bushing position and variable-length decapping rod enable precise resizing of any specified neck length segment
