I heard heavy recoiling rifles dislocates your jaw causing headaches. I get a headache every time I shoot my co-workers 338 Ultra mag that doesn't have a muzzle brake off the bench. I have heard to use a football mouth piece while shooting these heavy recoiling guns help keep jaw inline and cures headaches. Next time when I go out with co-worker I am going to try a football mouth piece and see it that works.
