Lyman Pro .45-70 Government Single Ammo Checker

Lyman Pro ammo checkers are precisely machined from corrosion-resistant stainless steel to meet minimum SAAMI chamber tolerances. Each Pro ammo checker is clearly labeled with the corresponding caliber. To use, simply insert your loaded cartridge into the gauge; if it fits, it will chamber in your firearm. This serves as an essential final check for competitive shooters or anyone seeking to ensure smooth and trouble-free chambering of reloaded ammunition.
