Accura bullets are constructed of only the best certified lead and copper. Bringing all the raw materials in house Accura begins by extruding the lead billets into wire. This is then put through their precise swage machines that uses pressure to form the lead core into the bullet shape. The lead cores are then shuttled over to the plating bath where the Accura proprietary plating process gives you the most malleable copper plating. Following plating the bullets are then put through one last sizing die that forms them to the final shape and makes them one of the most consistent and uniform bullets on the market.
