I built an indoor range to practice for NASP and bowhunting. It is 10 yards, shooting from the den into the garage. I like to challenge the kids with games to match or beat the coach. I cut the plywood length ways and installed four hinges. Put a rope loop to move it easy into position. Slides between the grey locker and the wall. Target will take up to 60 lb. draw weight. Target is from www.archerytarget.com in case you are interested. Photo attached.
Great idea going to make something similar. A 4x8 back stop on wheels. So the kids can shoot in the basement
10 yards in the basement is my plan too. I was wondering about a target handling 50-60#'s. At the camp, the compound I was using was set to 57 1/2 #'s and was putting arrows almost through at 50 yards.
