JSB Knock Out .25 (6.35mm) Slugs
JSB Knock Out in 6.35mm caliber is a heavy, expanding slug designed for the most powerful airguns on the market. Weighing 33.49 grains, this pellet delivers ballistics and impact energy that standard diabolo pellets simply can’t match.
Store tip: 6.35mm (.25) is a caliber that really benefits from a slug shape. JSB Knock Out retains its velocity much better over distance, making it superior for shooting at 50–100 meters and beyond.
Long-range precision
Unlike traditional waist-shaped pellets, JSB Knock Out features a streamlined slug profile. This gives it a much higher ballistic coefficient, meaning the pellet is less affected by wind and has a flatter trajectory. JSB is a world leader in ammunition, and its Knock Out series is the result of advanced manufacturing technology and strict quality control.
For owners of powerful PCP air rifles, this is often the ammunition that delivers the tightest groups. The hollow point ensures that all the energy is transferred efficiently to the target through significant expansion.
Don't forget the necessary accessories!
For an optimal experience with your .25 slugs, we recommend the following:
- Bulk purchase: Secure several boxes from the same batch to guarantee an identical point of impact over time.
- Maintenance: Powerful 6.35mm barrels require regular cleaning with a cleaning rod and oil to maintain accuracy.
- Safety: Remember that bullets in this weight class have a long range. Always use a safe backstop and wear safety glasses.
