both those articles seem to specifically address blows to the head. shooting a firearm under normal circumstances doesn't produce a blow to the head. my shoulder and torso take that jolt. the only force transmitted to my head is whiplash from a badly fitting or badly held gun. neither of my 500's have ever given me the slightest case of shooters headache (i.e. whiplash). however a ruger #1 in 458 is particularly bad in that regard. the factory #1 stock is not very good for heavy recoiling calibers.
