Lyman Aluminum Reloading Block (Standard Belted Magnum Family 0.565")

From Lyman

The loading blocks are CNC milled from a solid billet of 6061-T6 aluminum to tight tolerances for a close fit to specific cartridges, unlike the common one-size-fits-all plastic blocks and trays. The blocks are made in three sizes to fit most common rifle head sizes, and will hold 50 rounds. Blocks come with stick-on rubber non-slip feet to keep them from sliding on your bench.
