well if I was surviving in the wilderness and I had to live off buffalo, elk and moose then I would love nothing more than a 1903 but they are hard to come buy anymore, expensive, and the ammo is expensive. from a preparation phase, an enfield or mosin 91/30 would be much easier to get ahold of, way cheaper and mosin ammo is cheap and 303 brit ammo is moderate but acceptable. all three of these will kill anything in north america if you do your part. so
mosin cheapest option for stockpiling
enfield moderate pricing but still acceptable
springfield most expensive option but the best choice.
