Product description
JSB Knock Out 6.37 mm (.251) 33.49 grain slugs didn’t get their name for being lightweights. With 33.49 grain these 6.37 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 6.37 mm (.251) 33.49 grain slugs is 0.092.

The exact size of these slugs is .251 and one package contains one hundred and fifty JSB Knock Out 6.37 mm (.251) 33.49 grain slugs.

Perfect.

Review by Martin November 10, 2021

This slug shoots perfect in my two 0.25 Hatsans - the BT65 and the Blitz. Very fast delivery. Thanks Krale.

On a par with Nielsen.

Review by Steve November 21, 2020

I have been using Nielsen slugs for a while now and these Knockouts are on a par with them, same accuracy and hitting power!
