Blasting ARs on public hunting land

I'm hunting private land next to kisatchie national forest. There was an 8 pt on the edge of my shooting lane but I didn't have a shot. He was just looking up and down the trail. As he goes to step out, some yahoos let out a 10-15 round burst from their semi automatic weapon. Deer spooks and runs off. The shooter and his buddy proceeded to shoot at least 300 rounds for the next 2 hours nonstop. I understand it's public land and he isn't breaking the law, but what an a-hole. Go to a range if you want to play, let the men hunt. /endrant
