We were all over that range for about 3 hours.. there was a guy and his wife.. or a guy and gal..(I don't know if they were married or not) shooting next to us at the 25/50 yard range. I believe she was shooting a sks with brass ammo. I was kinda surprised when she left the brass casings laying on the ground and left. My daughter scooped it up pretty quick.. Lol
