The Hornady Universal Shell Holder #10 is a precision-machined steel reloading accessory designed to secure cartridges during the reloading process. This multi-caliber shell holder accepts a wide range of ammunition types—including .380 ACP, .221 Remington Fireball, 6mm TCU, .222 Remington Magnum, 7x47mm Helm, .20 Tactical, .204 Ruger, and others—making it a versatile choice for reloaders working with multiple calibers. Whether you're setting up a single-stage press or managing a progressive reloading bench, a properly sized shell holder is essential for consistent case positioning and safe, accurate rounds downrange.
Built from solid steel and heat-treated for durability, this shell holder is engineered to work reliably with Hornady's full lineup of reloading tools, including the Handheld Priming Tool and Cam-Lock Case Trimmer. Beyond the Hornady ecosystem, the #10 is designed to fit most popular press brands on the market, giving you flexibility if you ever upgrade or add equipment to your reloading setup.
Shell holders are often overlooked, but they're one of those foundational components that directly impact the quality and consistency of your handloads. A worn or undersized holder can lead to loose case seating, variable primer pocket engagement, and ultimately inferior ammunition. The Hornady #10's solid construction and wide caliber compatibility make it a reliable workhorse for serious reloaders.
