Underwood 357 Sig 115gr Jacketed Hollow Point Ammunition

Underwood Ammo has built a reputation for delivering reliable, effective handgun ammunition. This 357 Sig load pairs proven components with thoughtful engineering to create a round suitable for both defensive and target applications.

Nosler Assured Stopping Power Projectiles

The heart of this load is the Nosler Assured Stopping Power (ASP) bullet. These projectiles feature deep skives—precise cuts in the jacket—that work together to control expansion characteristics:

• Controlled Expansion: The skives create reliable, consistent expansion across a range of velocities and target materials
• Balanced Performance: Expansion is optimized without sacrificing accuracy or reliable feeding through semi-automatic actions
• Energy Transfer: Rapid expansion ensures energy is delivered to the target while minimizing the risk of over-penetration

Nickel-Plated Brass Cases

Underwood uses nickel-plated brass casings throughout this ammunition line. The nickel plating process delivers several practical benefits:

• Improved Feeding: Enhanced surface finish promotes smooth feeding in all firearm actions
• Corrosion Resistance: Nickel plating resists tarnishing and corrosion far better than traditional brass
• Storage Durability: Cases resist discoloration when stored near leather, moisture, and other metals
• Reloader-Friendly: The smooth, durable finish makes cases easier to process during reloading
