The 21545 Barnes Bullets are part of the VOR-TX Handgun hunting ammunition collection, featuring the exceptional XPB bullets. These bullets are noted for their double-diameter expansion, optimal weight retention, and outstanding accuracy. One of the key features of XPB bullets is their devastating effect on both tissue and bone, causing extensive destruction. In addition to this, they ensure pass-through penetration coupled with a devastating energy transfer.The speed of expansion is another distinguishing aspect of these bullets. They open instantaneously on contact, thus offering an unparalleled rapid expansion. This results in the bullet\'s nose peeling back into six sharp-edged copper petals that cause extreme damage to tissue, bone, and vital organs. Consequently, this results in a swift and humane kill.
