RCBS Single Stage Shell Holder #49 - .40-60/.45-60 - Ten-X Brass Only

The RCBS Single Stage Shell Holder #49 is a precision reloading component engineered for handloaders working with .40-60 Winchester Center Fire and .45-60 Winchester Center Fire cartridges. Designed for use with Ten-X brass only, this shell holder eliminates the need to purchase an entirely new single-stage reloading press when transitioning to these specialized vintage cartridge calibers. Whether you're a blackpowder cartridge enthusiast or a serious handloader seeking accurate ammunition for historical rifles, this accessory unlocks compatibility without replacing your existing press investment.

RCBS shell holders function as precision-engineered case positioning devices that secure brass in your single-stage press during the full reloading cycle—decapping, sizing, priming, powder charging, and bullet seating. The #49 model accommodates the larger diameter and unique dimensions of .40-60 and .45-60 cases, ensuring consistent case alignment and concentricity throughout all reloading operations. Built to RCBS's exacting manufacturing standards, this holder is machined to tight tolerances and designed specifically for Ten-X brass, which meets strict dimensional specifications for reliable performance across repetitive reloading sequences.

Blackpowder cartridge enthusiasts, cowboy action shooters, and historical rifle shooters benefit most from this shell holder, as .40-60 and .45-60 ammunition is not commonly available in factory form. Compatible with all RCBS single-stage presses (including the Rock Chucker and Partner models), the holder simply threads into the press head, making installation and caliber switching quick and straightforward. Handloaders should verify their specific press model for compatibility and ensure they are using Ten-X brass, as case dimensions vary between manufacturers and may affect fit and performance.
