JSB Knock Out slug pellets - designed for use in FACs. Thanks to the hollow point and the soft lead that JSB is known for, these slugs offer a very good expansion on impact.

5.5mm - 25.39 grains 

200 slugs per tin

These slugs are primarily designed to be used in FAC-rated air rifles. If you have a PCP below 12ft/lb, then please note that these may not fit the barrel or be suitable.
