In the picture below, my 13 grandson was able to shatter clay pigeons on the back wall of Jackson Pit using the Ruger PC carbine with iron sights. He was shooting cheap Federal 9mm 115gr bulk ammo. I called the first few shots so he could get dialed in. The hanging steel plates by the late IronMonster are 100 yards from the front of the table, with the back wall of the pit another 5-7 yards behind them.
