RCBS 9227 Single Stage Shell Holder #27 .357 SIG / .40 S&W / 10mm Auto

The RCBS 9227 Single Stage Shell Holder #27 is a purpose-built reloading accessory designed to properly align the cartridge case with your reloading die during resizing and other single-stage operations. Machined from hardened steel and finished in a silver tone, this shell holder delivers the long-lasting durability and consistent fit RCBS reloading tools are known for.

Sized specifically as #27, this shell holder is engineered to fit .357 SIG, .40 S&W, and 10mm Auto case heads, gripping approximately 0.125" of the case head to maintain proper SAAMI headspacing during the reloading cycle. It drops into virtually any standard single-stage or turret press and provides the secure case support needed for accurate, repeatable sizing, decapping, and bullet seating.

Whether you are reloading practice .40 S&W, working up defensive 10mm Auto loads, or running .357 SIG for competition, the RCBS #27 shell holder ensures your cases are held square and true so your dies can do their job. Made in the USA and weighing just 4 oz, it is a compact, no-nonsense addition to any handloader's bench.
