Here's my Target set up at home or one of them. This one is 30yds to the target pictured in the background. I use the kitchen Island as a bench shooting through an open window the other is 50yds and outside from fence to fence. The backstop is a Horse stall mat that was cut into sections doubled up with a space between (2x4). If a slug penetrates the first layer it bounces between the two layers and lands on the ground to be gathered up and melted into lead ingets.
