Nosler ASP .38 Special 125gr JHP ammunition (brand part no. 40137) is Nosler’s Assured Stopping Power defensive load, built for revolver owners who carry for duty or personal protection and want match-grade consistency behind a bullet designed to expand. Nosler skives the jacket at the nose, engineering the bullet to expand reliably across a range of impact velocities rather than only at full-power speeds. Loaded in Nosler-headstamped brass with the same attention to detail the company’s Match Grade line is known for, this .38 Special round balances accuracy with controlled, effective terminal performance. Concealed carriers and revolver shooters who want one dependable load for practice and protection alike reach for this ASP ammunition.

Key Specifications

• The caliber is .38 Special, one of the most common revolver chamberings for daily carry and duty use.
• The bullet weighs 125 grains, a proven balance of expansion and penetration for defensive .38 Special loads.
• The bullet is a Jacketed Hollow Point (JHP), designed to expand rather than pass through cleanly.
• Nosler skives the jacket at the nose, engineering reliable expansion across a range of impact velocities, not just at full power.
• Expansion is controlled, balancing penetration depth against energy transfer for effective terminal performance.
• The jacket mouth is shaped for smooth, reliable feeding, cycling cleanly through semi-auto conversions and reducing revolver reloading friction.
• Muzzle velocity runs 930 fps, a moderate speed that keeps expansion and recoil in balance.
• The cost works out to $0.97 per round, an accessible price for a defense-grade JHP.
• Each box holds 20 rounds, enough to combine practice and carry rotation.
• The case is Nosler-headstamped brass, loaded with the same attention to detail as Nosler’s Match Grade ammunition.
