I can only shoot at just under 20 yards in my basement and BR competition indoors is at 25 yards. I wanted to practice at the same distance I compete at. I thought about building a small extension onto the house (the addiction has no limits!), but decided that was a bit much. So, I came up with this idea. Works great. The target trap (box filled with rubber mulch) is in the box on the pedestal along with a light. The extension cord from the light goes through the tube. Now I can shoot at 25 yards "indoors". Here's a few pics. Last one is looking from the bench out through the tube.
