The Lyman Ammo Checker Block, 9mm, 100-Hole (Lyman part no. 7833036), gauges loaded ammunition to confirm it will fit a firearm’s chamber before it ever leaves the reloading bench. Machined from solid 6061 T6 aircraft-grade aluminum and cut with custom tooling to SAAMI minimum chamber dimensions, the block lets handloaders drop a loaded round in and immediately see whether it will chamber. Each caliber is clearly engraved on the gauge, and Lyman finishes it in bright orange anodizing so it’s easy to spot on a cluttered bench.
