Well some people can't tolerate recoil but want a chambering substantial enough for the job at hand. And a muzzle brake is a way to use a more powerful round with less recoil (other than having a heavier rifle). I respect Kansas for that.
Now, as for a muzzlebrake, any competent smith can put one one for you. But while it does reduce the amount of felt recoil, it greatly increases the noise factor - especially for those on the side of the shooter. There are MBs that open and close which is another option. Open for the range, closed for hunting.
