On 1 of my most memorable hunts I killed a gobbler based on someone target practicing. I was set up in an area for over an hour where I knew the birds liked to hang out. I was getting ready to leave when I heard a guy start shooting a pistol about a half mile off. All the sudden the ol' boy starting gobbling his head off. I sat tight and called him in. I also located one based on a guy hammering... sounded like he was hitting something on an anvil. The bird gobble every time he whacked it.
