Hunting club
With all due respect, the quality of hunting on a 250 acre parcel will diminish rapidly after just 10 hunters tramp through the woods.
I know they would not all be hunting at once, but with 25-50 members and their "guests", it would be chaos and safety would be a big issue.
I don't think it fair to call it a hunting club.
Likewise, the fishing would quickly go downhill too.
Perhaps a "Sportsman's Club" targeting the shooters, both target and shotgun, along with 3D archery. Bike paths, 4 wheeler trails, a small petting zoo or horseback rides can be held. A campfire at night draws in crowds and keeps them happy.
You could schedule fishing trips to other larger bodies of water nearby, winery tours, comedy nights, BBQ cook offs, nativity scenes.
Many opportunities out there to draw in members, but I would not call it a hunting club.
Best of luck-
