Lyman Custom Loading Block .445" Hole Diameter 50-Round Polymer

The Lyman Custom Loading Block is a purpose-built reloading accessory that holds up to 50 cartridge cases in a stable, organized grid for decapping, case preparation, and bench handling. The .445" hole diameter is precision-sized to provide a snug, secure fit for the family of cases sharing that case-head dimension, so each round stands upright without tipping or rolling during use.

Molded from a tough, durable polymer, this block is built to survive years on the reloading bench. The 50-case capacity keeps an entire loading session in a single, easy-to-grab tray, and the nested base footprint lets multiple blocks sit side-by-side or stack for compact storage. Lyman's Custom Fit Loading Blocks are designed as a precise fit for their target cartridge sizes, gripping each case by the head without squeezing the body.

Use the block to keep cases organized between sizing, priming, charging, and bullet seating on the reloading press. The polymer construction is gentle on case mouths and finishes, and the open-top design gives full access to each case for decapping or seating. Whether loading 50 rounds at a time or batching larger runs, the Lyman Custom Loading Block adds speed, organization, and repeatability to the reloading bench.
