The Hornady Shell Holder #37 for Trimmer (Item #390577T) is a case-preparation accessory designed for use with the Hornady Cam-Lock Case Trimmer. It holds the cartridge case securely in the trimmer head during the trimming operation, allowing the cutter to restore cases to the correct length with consistency and precision. Shell Holder #37 is sized to fit 5.7x28mm FN and .25 ACP cases, making it the correct choice for reloaders working with these smaller-diameter cartridges. Machined from heat-treated steel for durability, it locates the case by its rim in the standard Hornady fashion, where the cam-lock lever then locks the case firmly in place before trimming begins. The result is repeatable, accurate case length across an entire batch. Supplied as a single shell holder; the Cam-Lock Trimmer and pilots are sold separately. No firearms certificate is required — this is a reloading tool, not a firearm or ammunition component subject to UK licensing.
