The Berrys 00339 model represents Berry\'s Superior Plated bullets, which originate from a swaged lead core. Through the use of electrolysis in the plating process, the lead cores undergo tumbling in a bath that\'s electrically charged and contains high-grade copper ingots. As a result of this process, the copper adheres to the lead. The thickness of the plating grows directly proportional with the duration the bullets remain in the bath. Our precision ensures that our bullets are plated to the exact specifications before removing them from the bath.
