The Lyman Ammo Checker for .380 through .45 caliber handgun rounds (Lyman part no. 7833000) is a gauge that lets a reloader confirm in seconds whether a finished round, reloaded or factory, will actually chamber in their firearm before they ever load it into a magazine. It is machined from solid 6061 T6 aircraft-grade aluminum block and cut with custom tooling to SAAMI minimum chamber dimensions, so a round that drops freely into the checker and seats flush is sized correctly.
