I have a backstop that can be used out to 100 yds. I can also go out to 1000 yds if I wanted to. I used power/telephone poles that the local company was changing out. They were free and allowed me to bury them 3' in the ground two poles deep. They stick out of the ground 6' and have dirt piled in front. The best thing is the back side is straight up so no wasted dirt.
