The Nosler 51325 Assured Stopping Power (ASP) 9mm Luger ammunition delivers consistent terminal performance with 147-grain jacketed hollow point bullets engineered for maximum expansion and penetration. This subsonic load reduces muzzle flash and noise while maintaining the stopping power needed for personal defense applications.
What Makes This Different
Nosler's ASP line features proprietary bullet designs that expand reliably across a wide range of velocities, unlike standard hollow points that may fail to open at lower impact speeds. The 147-grain weight provides deeper penetration than lighter bullets while remaining subsonic for reduced signature. Each cartridge undergoes quality control testing to ensure consistent powder charges and bullet seating depth.
Key Features
- 147-grain jacketed hollow point bullets optimized for controlled expansion
- Subsonic velocity reduces muzzle blast and flash signature
- Nickel-plated brass cases for reliable feeding and extraction
- Low-flash powder formulation minimizes night vision disruption
- Consistent 950 fps muzzle velocity from 4-inch barrels
- Temperature-stable powder maintains performance in extreme conditions
- 50-round boxes with 10 boxes per case for bulk purchasing
This ammunition performs effectively in compact pistols and full-size handguns, with the heavier bullet weight providing better barrier penetration than 115-grain alternatives. The subsonic design makes it compatible with suppressed firearms while maintaining reliable cycling in most 9mm platforms. Law enforcement agencies and civilian users report consistent accuracy and reliable expansion in ballistic gelatin testing.
