The JSB .177 KO 13.43gr KnockOut Slugs are designed for high-power .177 PCP air rifles where maximum stability and long-range performance are essential. With a heavier 13.43 grain weight, these slugs deliver superior ballistic efficiency and reduced wind drift compared to lighter alternatives. Their elongated profile and optimised centre of gravity allow for excellent stability when fired from rifles with suitable twist rates and power levels. This makes them particularly effective for long-range target shooting and precision disciplines where consistency is critical. Manufactured by JSB using high-quality lead and strict quality control, each slug offers uniform weight, shape, and finish. When matched correctly to the rifle setup, the 13.43gr KO slugs provide impressive grouping, retained energy, and predictable flight characteristics. JSB .177 KO Slug Info 13.43gr 4.52 Tin of 400
