Winchester's Dual Bond technology welds the inner jacket to the lead core then takes a heavy outer jacket and mechanically bonds it to the inner bullet which results in deep penetration, exceptional knockdown power and weight retention close to 100%. Upon impact, the outer jacket deploys into 6 equal segments for quick and massive expansion. After penetration, the inner jacket opens into 6 segments to create a total of 12 segments for double the amount of expansion. This gives the hunter a round that delivers a clean, quick kill.
Designed to be used on medium-sized game like Whitetail deer or large North American game like the brown bear. This ammunition is new production and loaded in reloadable, brass cases.
