Shaman's advice is excellent. I say this because the one person I knew who actually hunted this way, wilderness hunting for days on end, did exactly that.
My grandfather was the only real survivalist I ever knew. He was not some kook, walking around marked trails with a hollow-handled knife strapped to his leg. He was a bit of a loner who had grown up in the depression bootlegging and hunting small game and to support the family. As a young man he became one of the original WWII paratroopers and survived a number of real survival situations, including being dropped miles from his objective and breaking his ankle in the process, and being MIA for 11 days in the Battle of the Bulge. When he got home he would "unwind" by cutting off a remote road in the Adirondacks and coming out when he damn well felt like it. As a matter of fact he did this, to some degree, until he died in his 80's.
Anyway, he was big on bulk items that could be used to fill the belly and provide protein, while spicing up whatever fare you happen to take along the way. I never knew him not to have eating utensils salt, pepper and Tabasco within arms reach. And I'm not kidding. he always had that stuff so that he could make any food tolerable. I guess once you've known hunger, you never want to go back.
Another thing he was big on was staging supplies ahead of time. He never packed stuff out of the woods. Once he brought it in he would bury the leftovers for the next trip. He did this with equipment as well. I remember riding along the Blue Ridge Road in Essex Co. NY and having him pull over and direct me back into the woods to retrieve a sheet of tin that he wanted to use as a shield for our campfire. I'll never know how the hell he remembered where all that stuff was. I suspect that there are a few tons of flour, beans and a few gallons of whiskey scattered around the forests of the central Adirondacks if anyone wants to go looking.
With all that said, Gramp was a spec. ops. vet from another era. The guys today are all about ligtweight, high calorie, and high protein. Remember, they patrol the highlands of Afghanistan on one MRE a day. While you may think you are starving, an MRE has enough nutrition to sustain you for longer than you think. Yes they get old, so you may also want to consider the commercial alternatives that are made for backpackers.
Sounds like a cool way to do things. Have fun and let us know how it comes out.
