It's extremely short sighted and naive to think you can just up and move to a country and live off the land, land that is in most cases owned by someone else.
Unless you are hunting big game like deer, boar etc it's going to be extremely difficult to kill and forage enough to keep you in sustenance.
You also have to think about purchasing ammunition, gun licenses, repairs, maintenance, getting to and from hunting grounds.
You'll also have to find some way of making the meat last.
You then have to think that there are very very few areas where you are allowed to hunt anything, all the time, so you will have to hunt only what is in season, so that'll often mean travelling to different areas.
There is also the time involved, it takes time to learn how a species acts, where they sleep or roost, where to find them at certain times of the day, where to aim to kill them quickly.
You'll also need to be a good marksman, and with lower powered guns or easily spooked game, a good stalker, this again needs time and patience.
Even if you have the skill, knowledge, finances and permission to hunt on some land, how long do you think you can hunt before a certain species becomes wise or you've killed them all in that area?
Then there is your health to consider, if you are eating the same meat every day from the same area it's not going to be the healthiest way to live.
Even if you have money for medical care, what happens if you are laid up with flu for 2 weeks, who will supply you with food then?
No doubt that there are folks in areas of the world that do live off the land, so it is possible, these people have built up their knowledge and skills over many years though, they often have communities around to take up the slack when illness strikes.
