Made specifically for the box magazine AR-15, this bullet is made with pure copper jackets, pure lead cores, and are available with varying degrees of skiving to enhance expansion for your loads. It stands up to the rigors of auto-loading with sturdy construction that supports high velocity loads yet with added skiving, expands at lower velocities too. Expect delivery by the end of the month following the month purchased in. When inventory is exhausted, back orders are taken and filled in the order they were received. Bonding is currently under development as is an optional cannelure ring.
