H&N Slug HP Heavy .218 Airgun Slugs (40 Grain / 120 Count)

The H&N Slug HP Heavy (Hollow Point) in .218 diameter represents the heavy-weight tier of H&N's precision big-bore slug lineup. Specifically engineered for extreme-power Pre-Charged Pneumatic (PCP) air rifles, these slugs feature a solid, elongated bullet-like profile designed to withstand massive air pressures without destabilizing. At a substantial 40 grains, this projectile is built for maximum energy retention, providing a devastating choice for ultra-long-range benchrest shooting, heavy pest elimination, and medium-game hunting at distances well beyond 100 meters.

Ballistically, the Slug HP Heavy is designed with a massive hollow point opening and a broad meplat. Combined with H&N's specialized, ultra-soft lead composition, this design ensures rapid, immediate mushrooming and massive shock transmission upon target impact, even at lower terminal velocities downrange. Its .218" sizing ensures an optimal gas seal and tight engagement with the barrel rifling, maximizing compression and muzzle energy. Boasting a remarkably high ballistic coefficient for a flat, wind-defying trajectory, these heavy slugs are meticulously sorted, visually inspected, and packed in foam to ensure perfect shot-to-shot consistency.
