This is Extreme Shock 32 Auto 60gr. Enhanced Penetrating Rounds (EPR). The Enhanced Penetration Round (EPR) was engineered for applications where greater penetration is a must. The EPR has greater terminal success through glass and wood to maintain the lethality of the round. This round has the ability to penetrate heavy skin, dense bone, and then fragment once inside the softer tissue of the target.  This ammo is packed in 6rd. packs.
