It is. Your KK500 will do that or better nearly every time with the factory barrel. Mine came with an 11mm factory target group (outside to outside measurement) @ 50 meters which translates to less than 10mm @ 50 yards. I've bested that at least once, and it shoots one hole with almost every premium brand that I've tried. These results are for indoor. I'm surprised more people don't use it for benchrest.
