The JSB KnockOut Slug is a .22 calibre (nominal .217 inch diameter) hollowpoint slug made from soft lead and designed specifically for higher-powered PCP air rifles. Weighing 25.39 grains and measuring 8 mm in length, each slug delivers a verified ballistic coefficient of 0.084–0.086, giving outstanding energy retention at range — independent testing confirmed over 74% of muzzle energy retained at 100 yards. The hollow-point cavity collapses on impact to expand the slug dramatically, with tested expansion from 5.55 mm up to 9.29 mm diameter, making these an effective choice for pest control and hunting where a clean, decisive result is required. The slight undersize nominal diameter of .217 inch is deliberate, reducing barrel friction over the slug's longer contact area compared with a traditional skirted pellet. Slugs are packed in a 200-count screw-top tin with a foam spacer to protect them in transit. Made in the Czech Republic by JSB, a manufacturer with a long-established reputation for consistent airgun ammunition.
