what first?

If you see your problem as a lack of food due to no work, air rifle. You are more likely to get permission to take rabbit and pigeon than you are deer or boar. Also, although it is armed tresspass and a stupid crime to commit as - armed response will turn up and might shoot you, your stuff will be confiscated and destroyed and you run the risk of jail, I still see an awful lot of evidence of people shooting with air rifles on public land.

Do not discount something such as a catapult. Easy to put in your coat, not going to see you in jail and you were just firing stones at cans. The way people are these days if you have a bow and are not firing it into a paper target or if you have a crossbow with you on public land, expect a call going into some one.

As for self defense, you should not really have any of that kit for self defense, shows intent see. You had it because you like to have it for other reasons.

Buy yourself a nice light but strong chair to put your watch on or hang your pants off in the bedroom.
