Would this be a completely un-resupplied walkabout?
Please be advised that it is not possible to survive on "small game" alone. The natives who attempt that in Canada develop a condition known as "Rabbit Starvation" simply because people can't make it on a diet consisting solely of lean meat, as is found in small game.
Big game is another deal. That will do nicely for you. The meat from big game has sufficient fat content that you can survive on a 100% meat diet. This calls for a technology that will reduce big game to possesion. This seems to me to cry out for a center-fire rifle.
I would suggest that you try out this enlightening exercise:
On large pieces of paper(like butcher paper or poster boards) draw lifesize simple pictures of animals. Copy them from a household encyclopedia and take your time drawing. You'll be surprised how well they'll turn out. Then place them at "unknown" distances and shoot them in the vitals from a semi-awkward standing position, under minor time constraints. Your weapon system must be able to deal a telling blow, in a timely manner, or it's no good.
It's a good excuse to go shooting, too.
My liberal FemiNazi cousin was thrilled to shoot at lifesized pictures of California Quails, with a Nazi surplus 9mm. 'Nother sheeple converted(at least a little bit.)
Once you are convinced, get a hunting license and try out your ideas on the real deal. Very eye-opening. Was for me, anyhow.
Cheers
