An old saying goes, “you get what you pay for.” With K.O. slugs, that’s not entirely true

You get a lot more than you pay for. Since their introduction well over two decades ago, hunters have come to value K.O. performance as much as their reasonable price. An improved Foster design, in both 12 and 20 gauge, provides deadly knockdown power and terrific accuracy. Their specially designed wads generate high velocity and a  remarkably flat trajectory. And, all K.O. slugs are equally at home in rifled or smoothbore barrels.

20 gauge shooters give up very little to their 12 gauge brethren when shooting K.O. 20s. In fact, they’ve become so popular, they outsell many of our 12 gauge loads. K.O. 20 gauge are an ideal choice for deer at medium ranges, retaining strong velocity and energy over a flat trajectory. Whichever gauge K.O. you choose, you can be sure of one thing: they pack a punch.

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.
