GOLDEN 20-POCKET GAUGE - 40S&W

Any competitor serious about his shooting is aware of the importance of drop-testing one´s bullets before a match. Since most malfunctions are ammo related, and most of those relate to deformed, bulging or otherwise defective brass - dropping the bullets into a gauge is an effective way to reduce the chance of a costly malfunction. The problem has always been that it takes time! over 15 minutes at least, to test 400 rounds with a single bullet gauge or using one´s barrel. Well not any more!
