Hornady Handgun Hunter 357 Magnum 130gr MonoFlex ammunition comes as a box of 25 rounds (Hornady part no. 9052) built around the company’s MonoFlex handgun projectile. Hornady makes the MonoFlex from a tough copper alloy that it says achieves deep penetration and 95% weight retention. An elastomer material sits in the open cavity of the bullet, so on impact it compresses, then pushes out and drives expansion faster than a standard hollow point design. This 130-grain 357 Magnum load is part of the Handgun Hunter line, which Hornady built around a bullet as rough and rugged as the conditions and game demand. Premium cases, primers and propellants round out the cartridge for field use.
