JSB KNOCK OUT MKIII .177 AIRGUN SLUGS 10.03GR 4.51MM (X500)

The JSB Knock Out MKIII .177 Airgun Slugs 10.03gr 4.51mm are precision-made hollow point slugs designed for shooters who want flatter trajectories and strong downrange performance from suitable PCP air rifles. This MK3 version uses a 4.51mm diameter, 10.03 grain weight and 500-count tin, making it a practical choice for regular long-range target work and hunting where legal. Compared with a traditional diabolo pellet, the JSB Knock Out MKIII slug shape holds velocity better in flight, helping improve stability and energy retention at distance. Soft lead construction and the hollow point profile are intended to give reliable expansion on impact.
