I've got 4-5 targets in different places in the backyard, and never measured how far any of them are from wherever I shoot. Didn't even occur to me to consider doing that until I read your post. Of course, since there are a limited number of places I can put targets in my backyard, and a limited number of places I can shoot them from, I have them all pretty much dialed in anyway. I wish I could shoot them from my roof. It would be totally safe, but neighbors and people driving by on the street behind my house could see me and might take issue with that. Issues that I would just as soon not have.
