Elite Performance ammunition, with V-Crown Jacketed Hollow Point bullets, is designed to provide superior accuracy, reliability, and performance in a personal defense round. The Sig V-Crown stacked hollow point design provides a smaller, additional hollow point cavity behind the main cavity. This design, along with V-shaped jacket skives and scores, provides controlled, uniform expansion at all effective distances and velocities. The bullet has a unique toothed cannelure halfway up the shank to more effectively lock the jacket and core which provides exceptional structural integrity in a jacketed design, ensuring maximum weight retention and outstanding terminal performance. Brass cases are Techni-Crom coated for enhanced lubricity, superior corrosion resistance, and reliable feeding and extraction. Each caliber loading of Sig Sauer Elite Performance Ammunition is precisely matched to the core temper of its Sig V-Crown bullet to ensure maximum terminal performance.Specifications:Manufacturer: Sig SauerModel Number: E357S1-20Ammo Bullet Type: Jacketed Hollow PointAmmo Casing Type: Nickel Plated BrassAmmo Bullet Weight: 125 grainAmmo Round Count: 20/BoxCaliber Multi: .357 SIGMuzzle Energy: 511 lb/ftMuzzle Velocity: 1356 fpsApplication: Personal DefenseSeries/Collection: Elite Performance V-Crown
