RCBS Full Length Die Set .357 Sig - 23101

This two-die reloading set for .357 Sig bottleneck cases includes a Full-Length Sizer Die with Expander-Decapping Unit and a Seater Die with Bullet Seater Plug. The sizer die brings cases to SAAMI minimum dimensions, sizes the case exterior, de-primes, and expands the neck to accept bullets, with vents to prevent case damage from trapped air and excess lubricant. Headspace is held to minimum tolerances to ensure consistent cartridge dimensions.
