EGW 7-Hole Cartridge Checker Features Out of specification ammunition is the root of jams misfires and feeding problems and the EGW 7-Hole Cartridge Checker is designed to catch those rounds at the bench instead of on the firing line. Each pocket measures minimum case diameter and maximum overall length at the same time so a round that drops in flush is confirmed on both of the dimensions most likely to cause a stoppage. The seven hole layout turns checking into a batch operation letting a reloader run a full tray of finished rounds through in handfuls rather than one cartridge at a time. For high volume .223 Rem loaders that speed is what makes the check something actually done on every round instead of a spot inspection. Because the chambers are cut with genuine Clymer reamers the checker reflects real chamber geometry and gives an honest pass or fail rather than a loose approximation. The 6061 T6 aircraft grade aluminum body is light enough to live in a range bag yet rigid enough to keep its dimensions and the matte black anodized finish resists the scuffing and corrosion that come with constant handling. It works equally well as a final step in a reloading process and as an incoming check on factory ammunition of unknown history. For competitors instructors and reloaders who would rather find a bad round on the bench than in a match the EGW 7-Hole Cartridge Checker is available for sale at GrabAGun.
