Berry's Bullets Now In-Stock. We've had several customers request we carry Berry Bullets, so we laid in a small line of their plated bullets. Berrys has been around for over 50 years and is pretty well known in the reloading arena. They make over 60 styles of premium bullets. Berry's Premium Plated bullets begin as a swaged lead core. The plating process works through electrolysis. The swaged lead cores are tumbled in an electrically charged bath containing high-grade copper ingots. The copper clings to the lead and the longer the bullets remain in the bath, the thicker the plating. Their bullets are plated to the correct size and then taken out of the bath.
