JSB Knock Out .22 (5.5mm) Slugs
JSB Knock Out is a heavy, expanding slug designed to deliver extreme power and precision. Weighing a full 25.39 grains, it’s the choice for shooters who demand maximum impact energy at long range.
Store tip: Slugs perform differently from traditional diabolo pellets. They often require more power (PCP rifles) and a barrel that can handle heavier ammunition to deliver the extreme precision they’re known for.
Extreme Expansion and Ballistics
Unlike standard airgun pellets, JSB Knock Out has a slug shape that more closely resembles bullets used in firearms. This results in a much higher ballistic coefficient, meaning the slug retains more energy over longer distances and is less affected by wind. The hollow tip ensures controlled and powerful expansion on impact.
JSB is recognized as the world’s leading manufacturer of airgun ammunition.By choosing the Knock Out series, you get the same uncompromising quality in materials and production processes that has made JSB the first choice for competitive shooters worldwide.
Don't forget the essential accessories!
For the optimal experience with your JSB Knock Out Slugs, we recommend the following:
- Bulk purchase: Buy several boxes at once to ensure you get ammunition from the same production batch.
- Maintenance: Use silicone oil or cleaning equipment regularly to prevent lead buildup in the barrel.
- Safety: Always wear approved safety glasses and ensure you have a safe pellet trap capable of withstanding the force of heavy slugs.
