Lyman 7728086 Precision Loading Block for .308 Winchester, .485" Diameter

The Lyman 7728086 Precision Loading Block is a .308 Winchester-specific reloading accessory engineered to make ammunition preparation faster and more comfortable. If you're a handloader working up rifle loads for .308 Win or any of the other rifle calibers that share the .485" cartridge head diameter, this stepped design block cuts fumbling and finger fatigue out of your reloading routine. Built from durable polymer and sized to hold 50 rounds, it's a bench upgrade that actually saves space and makes the process smoother.

The Bleacher Block concept addresses a real pain point in traditional loading blocks: reaching down into tight rows of cases to grab a single round without pinching your fingers. The stepped design creates natural access points at different heights, so you can comfortably pick up cases from the top without jamming your hand into a crowded hole. It's a small detail that adds up over the course of a long loading session.

The .485" hole diameter fits a wide range of rifle cartridges beyond .308 Winchester—everything from .223 Remington and .22-250 up through magnum cases like .300 Win. Mag. and .338 Federal. Because the block is molded specifically for this case-head size, cases seat snugly and stay put while you're working, reducing the chance of spilled rounds and wasted time.

Whether you're a volume reloader turning out match ammo or a hunter loading precision rounds for next season, a dedicated loading block keeps your process organized and your workspace efficient. This one earns its place on the bench through thoughtful design that respects your time and comfort.
