I think the only question here is: Is it hunting or just killing? Actually to me deer are just long legged rats ( is that sacrelegious) But I have to contend with about 25 of the buggers all winter destroying everything they can reach.I have no doubt Boyd can do as he says. I saw similar shooting way back in 58. A close friend use to shoot whiteail with a .38 Norma MAg at extreme distances. I couldn't for the life of me reason why someone needed such a big cartridge for a 150 lb deer I don't have any problems with this, just don't call it hunting.
