Lyman Custom Fit Loading Block .485 Hole Size Fits Select Calibers

The Lyman Custom Fit Loading Block with .485 hole size is a precision reloading organizer designed to streamline cartridge staging and component management during ammunition loading operations. Built from durable polymer construction, this loading block securely holds 50 cartridges in properly sized cavities and nests with other Lyman blocks for compact storage and transport—essential for reloaders who manage multiple caliber families and require consistent, repeatable organization at the bench.

The .485 hole diameter accommodates a range of medium rifle cartridges including .225 Winchester, .22-250 Remington, and similar bore sizes. This precision fit prevents cartridge roll-off and contamination during the loading sequence, reducing lost rounds and maintaining indexing accuracy. The clearly marked hole diameter on each block eliminates operator confusion when switching between caliber families, a critical safeguard in high-volume or multi-stage reloading workflows. Dimensions of 5.65 × 1.3 × 7 inches provide efficient bench footprint while maintaining stable platform geometry. The lightweight construction (0.3 lbs) allows operators to rotate multiple blocks without fatigue during extended loading sessions.

This block is purpose-built for handloaders, precision rifle shooters, and ammunition developers who require dependable cartridge organization. Whether staging components for ladder testing, batch loading, or preparing ammunition for field operations, the Custom Fit Loading Block ensures each round is positioned consistently and protected from handling damage. Available in six size variants across the Lyman catalog, operators can build a complete system tailored to their specific cartridge portfolio—from .224 through larger magnum bores—without overbuying unnecessary blocks.
