Safety Of A Quick And Clean Kill:

The K.O.™ gives you the safety of a quick and clean kill, even better as it is one of the least expensive slugs on the market. It offers 58 % more frontal area than standard .50 cal slugs, resulting in massive energy transfer. Deep penetration, expansion up to .9”, you name it, the K.O.™ got it.


Available calibers
12 GA 2¾"(437 grs)
20 GA 2¾"(328 grs)

The K.O.™ produces extensive damage in the first block of ballistic gelatin, expending virtually all of its devastating energy within the first eleven inches.

Controlled penetration (only two point five inches in the second block) limits liability on unintended targets.

Excellent 20 GA K.O. precision

The shotgun are supported; and as you know, the Accuracy depend on my shotgun open sight, but the precision, depend on the bullet. In this case; at 50 yards, is already 5 MOA. For hunting purpose, this precision is enough.
Thanks for the quality of the products of your company.

Merry Christmas and a happy new year for you and your family.

Remark from Brenneke: To archive such a group at 50 yards with open sights, it needs an excellent shooter. Just imagine what the accuracy would be using a scope.
