Airgun Slugs Nielsen 5.5 mm 36 grain
Unleash unmatched power and pinpoint accuracy with the Nielsen 5.5 mm 36-grain airgun slug—engineered to elevate your shooting experience with every trigger pull. Designed from the ground up for the semi-automatic Huben air rifle, these slugs deliver seamless feeding, razor-sharp trajectories and consistent down-range performance.
From the moment you load the flat-base, hollow-point slug into your magazine, you’ll notice the difference. Its precision-machined profile glides effortlessly into the chamber, eliminating jams and ensuring smooth cycling shot after shot. Once fired, the hollow-point tip expands reliably on impact, transferring energy where it counts and delivering decisive results on small game or your paper target.
What truly sets Nielsen slugs apart is their manufacturing excellence. Each 36-grain pellet is swaged from ultra-soft, high-purity lead to achieve an exacting weight and uniform shape. This meticulous process yields virtually zero variance between slugs, so your groups stay tight and your point of aim remains rock solid. Whether you’re zeroing in on a distant bullseye or gauging ballistics for a hunting excursion, you can trust these slugs to behave identically every time.
Versatility is another hallmark of Nielsen’s design. While optimized for the .22 Huben, the 5.5 mm slugs also perform flawlessly in any air rifle chambered for .223 or .224-inch projectiles. That means one premium slug fits multiple platforms, saving you time and money while maintaining optimum performance across your entire arsenal.
Soft‐lead construction not only enhances consistency but also reduces barrel fouling and minimizes wear—keeping your rifle in peak condition and cutting down on cleaning intervals. Plus, the flat base design gives each slug a stable launch platform, translating to superior down-range stability and energy retention.
Whether you’re a competitive shooter chasing personal bests or a dedicated hunter demanding reliable terminal performance, the Nielsen 5.5 mm 36-grain slug is your ticket to exceptional results. Experience the confidence that comes from using ammunition crafted with purpose, precision and passion.
