Absolutely agree with you. I know guys who have hunted deer for many years without making a kill. They think if there is a shift situation they can provide by hunting! How? Are they going to become good hunters because they have no other options?I am of the thought that hunting for food will not work. I store food or prep for when it isn't around to buy. When I hunt I hunt with a 358 Winchester most of the time on large game. Shotgun for small game. I don't see that changing if things go bad. I hunt on my land.
The same guns I hunt with can be used to protect our place. I live in the country and most of the people out here have guns and grow food. They also put food back so they have it till the next growing season. It has been dun this way before I was born and it will be dun the same way long after I am gone. They don't call it prepping they call it farming.
Also it is in bad taste to hunt on other peoples places with out asking. It can get you put in jail. With the lack of law I would say it could get you shot.
No way in hell do I want to go to a national forest and hunt for food. That is dangerous enough when things are good. I have no idea what it would be like if things went bad wrong.
To your second point. As a farmer (the real kind. Not the kind with 5 acres, 6 chickens, and a goat named nanny) I take trespass seriously. In a lawless society the hunter could become the hunted. The best solution for the op is to learn how to garden and preserve. Then buy a 12 gauge to protect his food and home.
Don’t even get me started on bugging out. Lol
