Additional Information:
The Barnes all-copper X Bullet is specifically engineered with razor-sharp petals to produce massive wound channels even in dense, thick-skinned game. They expand rapidly, dump more energy and penetrate deeper than any lead-core bullet available. Copper, non-toxic bullets expand into 4, five or six cutting petals that tear through tissue and give ideal terminal performance for good clean kills.
