Dude, the place to ask is local and not the internet. Get to know people who shoot, hang out at the local shops, competitions, bars, restaurants, town meetings, etc.

Those friends and acquaintances will be the helpful folks in your area instead of a bunch of randos spread throughout NH.

Furthermore, this is reddit, which is about as sketchy and anonymous as it can get and not be one of the chans. If you want internet help on items like this, the place to ask are forums or FB groups after being an actual participating member.

NH law is quite permissive when it comes to shooting on public land. The laws have been posted a gazillion times by me and others. RSAs 207:3A, 207:3c, and 644:13

What you need to understand is that “nice guys” ask this question about 15x a week. Almost every single time any one of us has given a spot to the newest “nice guy” it has gotten absolutely trashed either by them, their stupid friends, or them passing said spot on to assholes.

So many of the nice spots to shoot have been destroyed by guys who say the same things on the same posts. You’re barking up the wrong tree asking here. Scout out some good spots for yourself and then keep them private if you want them to last. I’m not upset at you per se, but it’s annoying seeing people day in and day out being pissy that nobody will give them their spots to shoot. Do like everyone else and put the work in to scout out a spot.
