Mate it shouldnt make any difference, thats the great thing about shooting and air rifles in particular it doesnt matter if your rich or poor. As long as you present yourself well the land owner will not know where you are from, give it a go and I am sure that you will end up with some permission, it will be more enjoyable as you dont have to worry about getting arested every time you go out, and also if you are caught you could be kissing good bye to shooting for the rest of your life so it makes sense
good luck
