The Nosler 51271 Assured Stopping Power delivers consistent terminal performance in a 185-grain jacketed hollow point configuration. This premium 45 ACP ammunition combines Nosler's precision manufacturing with proven hollow point expansion technology. Law enforcement and civilian users rely on this load for situations demanding reliable stopping power.
What Makes This Different
Nosler's Assured Stopping Power line features engineered hollow point cavities that promote controlled expansion across various barrier materials. The 185-grain projectile achieves optimal velocity while maintaining manageable recoil in standard 45 ACP platforms. Premium brass cases and consistent powder charges deliver shot-to-shot uniformity that exceeds typical range ammunition standards.
Key Features
- 185-grain jacketed hollow point bullet optimized for expansion
- Premium brass cases with consistent wall thickness
- Engineered hollow point cavity for reliable terminal performance
- Standard velocity loading compatible with all 45 ACP firearms
- Quality control testing ensures consistent ballistic performance
- Boxer-primed cases suitable for reloading

Field testing demonstrates consistent expansion characteristics through common barriers including denim and wallboard. The 185-grain weight provides sufficient momentum for penetration while the hollow point design limits over-penetration concerns. This load functions reliably in both full-size pistols and compact carry guns chambered in 45 ACP. Temperature stability maintains performance across seasonal conditions.
