Don't let the liberals get you down. Your ownership helps them in the long run, even if they don't understand enough history to realize it yet.
The most prestigeous yacht club in our area shoots clay pigeons off the dock all winter long. I've been invited but I'm always busy doing boat stuff or actually sailing. Nice people, have met a bunch of them and may one day join the yacht club. There's a few more clubs that I know about that do the same thing. It's seems an active part of yacht club life up here.
We shoot clay pigeons off the beach in out near the end of Long Island. Police said it was ok, we called and asked before doing it the first time. Their attitude was "Of course it's ok, now stop calling to ask things like that." We got the launcher and everything, so it's quite an enjoyable way to get out of the house in winter. There are a lot of limosine liberals out in the Hamptons. When shooting off the beach and your run of the mill liberal walks by I always offer to let them have a try. Yes it's fun for them and they go away hopefully more educated and familiar with those things that the liberal press told them was bad their whole lives.
When out shark fishing once, 20 miles offshore, our captain talked about NYC cops onboard that were trying to shoot jumping fish with their handguns. I'm not a big fan of bullets over water because bullets can skip. But if you can't see any boats for 6 miles you've got to be ok. Even the most robust rifle won't skip a bullet that far, AFAIK
Lead shot is ok in salt water. Steel shot is for inland wetlands where the lead would make a big negative impact. (Actually I'm not a fan of lead shot anywhere inland except ranges, since it's getting spread around on the top layer where everything lives.)
As for glass? It's made from sand, right? Enough said, except make sure you remember who gave you the advice that glass is not OK to put on the bottom of the ocean 12 miles out. (Plastic is a whole different story; you need to bring home every bit that you left with. I sometimes scoop up floating plastic bags with a dock pole and dispose of it on shore.)
