Federal's Premium Law Enforcement HST line of JHP duty ammunition offers massive expansion! This duty load has a pre-skived bullet tip which causes the bullet to expand into large petals that cause a large permanent wound cavity. The unique design of this bullet actually forces the lead petals during expansion to protect the copper petals behind them. This results in increased weight retention allowing it to still achieve deep penetration through a variety of barriers prescribed by the FBI test protocols.This product is brand new, nickel plated brass-cased, boxer-primed, non-corrosive, and reloadable. Maximun 20 boxes per order.
