RCBS Full Length Die Set 221 Fireball - 10801

This two-die reloading set is designed for bottleneck rifle cases and 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 for bullet acceptance, while vents prevent case damage from trapped air or excess lubricant. The set maintains minimum headspace tolerances for consistent reloading results.
