The Redding Competition Shellholder Set gives you control over headspace and enables you to perfectly match the headspace of your reloaded ammo to any gun. This set consists of five shellholders in varying heights with increments of .002″, offering five piece sets in .002″ increments (+.002″, +.004″, +.006″, +.008″ and +.010″). Each shellholder has a distinct black oxide finish and is clearly marked to indicate the amount it will change case-to-chamber headspace—no special tools or gages are needed.
Unlike standard shellholders, this competition series is meticulously manufactured to tighter tolerances, designed to provide a uniform .001″ greater clearance between the case head and the shellholder, which helps to properly size cases while minimizing force on the cartridge case for more consistent shoulder setback and uniform loaded ammunition. You can easily adjust the shoulder bump to customize cases to your specific chamber. Once the proper shellholder is determined your results are repeatable and no die adjustment is necessary.
This set is specifically calibrated for a range of large and magnum cartridges including .338 Lapua Magnum, .300 Lapua Magnum, and .416 Rigby, among others. Manufactured from premium, heat-treated steel, this shellholder set is built to withstand the rigors of frequent reloading, with durable construction ensuring a long service life while maintaining its precise tolerances even after thousands of reloading cycles. Storage box included.
