KnockOut Slugs 2,170 g precision, homogeneous bullet with high Ballistic Coefficient (BC): 0.092. Heavy super-caliber shot in .251 / 6.37 mm caliber with a deep recess on the face to increase the toppling / tearing effect. Unlike classic Diabolo, Slugs have a shape similar to firearm bullets. As a result, it loses less velocity during flight and thus achieves a flatter trajectory. Designed for the most powerful air rifles in the FAC (no energy limit) version for accurate shooting at long distances (not sensitive to wind gusts) 50 meters, 100 meters and even 200 meters.
