Lyman Custom Fit Loading Block .530" 50-Rd Polymer - Fits 284 Winchester

The Lyman Custom Fit Loading Block is a bench-top reloading accessory designed to keep freshly sized and trimmed cartridges organized between steps. Sized to a precise .530" hole diameter, this block is built to hold 284 Winchester cases - up to 50 cartridges at a time in a single block.

Molded from a tough, durable orange polymer, the block stands up to repeated handling on the loading bench without cracking or warping. The base is cut so multiple blocks securely nest together for easy storage, letting reloaders stack and organize batches across multiple calibers without wasting valuable bench space between reloading sessions.
