Hornady 357 Mag 130gr Monoflex Handgun Hunter (9052)  

Hornady Handgun Hunter® ammunition is built around a bullet as tough as what is demanded from it. The MonoFlex® handgun projectile is manufactured with a copper alloy that achieves deep penetration and 95% weight retention. Bullet expansion across a range of velocities is aided with an elastomer material added to the bullet’s open cavity. Upon impact, the elastomer compresses, then pushes out and causes the bullet to expand faster than a standard hollow point design.
