Nielson Ammo 15.5 gr .177 Slugs

Nielson Ammo 15.5 gr .177 Slugs

Unlock the full potential of your .177 PCP air rifle with NIELSON AMMO’s precision-engineered 15.5 grain slugs. Crafted from soft, pure lead and swaged to razor-sharp tolerances, these slugs deliver unrivaled accuracy shot after shot. Whether you’re stalking small game at dawn or fine-tuning your target setup in the backyard, these hollow-point pellets expand on impact for clean, humane kills—making every hunt more responsible, efficient, and satisfying.

Meticulously tested in Daystate factory, LW, and TJ barrels, NIELSON’s .177 slugs have proven their consistency in real-world scenarios. You’ll experience tight shot groups, consistent trajectories, and the reassuring knockdown power you need to connect on fast-moving targets. And with a ballistic coefficient of .062, they slice through wind drift and maintain energy even at extended ranges, so you can push your rifle farther and still hit your mark.

Designed with a flat base for rock-steady flight and a 2S hollow-point nose for maximum expansion, each slug measures .266 inches in length and weighs precisely 15.5 grains. They’re optimized to feed smoothly in most break-barrel and PCP rifles—just be sure to pair them with Daystate or the new FX X-Barrel. (Important: avoid using these slugs—or any solid bullets—in original Smooth Twist FX barrels to prevent damage.)

Every pack contains 100 premium slugs, ready to go from your bag to the barrel. Whether you’re a seasoned hunter or a precision-obsessed target shooter, you’ll appreciate the combination of velocity, energy transfer, and pinpoint consistency that only NIELSON AMMO can deliver. Elevate your next outing with slugs that inspire confidence—take aim, pull the trigger, and watch your performance soar.
