These new JSB Knockout or Knock Out air gun pellets are 5.5 mm slugs that didn’t get their name for being lightweights. With 25.39 grain these 5.5 mm slugs are heavyweights for sure.  Thanks to the hollow point and the soft lead JSB is known for, these slugs offer a very good expansion on impact. The ballistic coefficient of these JSB Knock Out 5.5 mm 25.39 grain slugs is 0.084. The exact size of these slugs is .216 and one package contains two hundred JSB Knock Out 5.5 mm 25.39 grain slugs.

We only recommend these slugs for use in FAC air rifles.
