The Naturalis is made of pure copper. As a premium hunting bullet it performs consistently, retaining  a full 100% of its weight after expansion almost every time. The material, design and controlled expansion ensures a solid and nearly unbreakable construction. It provides maximal shock effect and works perfectly within terminal velocities of 490 m/s to 1000 m/s (1607 fps to 3280 fps). The boat tail design eases reloading, and together with the streamlined ogive provides improved downrange ballistics. It doesn’t leave anything in your valuable game meat, so with Naturalis, you get a clean shot.
