Stupid question here - why would an optical setup not see the hole? After all, is that not how the shooter found the bulls eye to begin with, through an optical scope. Regards - Mike

Hi Two gotchas, one minor, the other a bit bigger. At 800 yards, even a *very* good optical setup can't / won't see holes in a target. The atmosphere is just to unstable. You would have to mount the camera down range (minor issue). The larger one is that you really don't want to truck down a half mile of path to put up a new piece of paper. After a while the "target" gets pretty ragged. There's not much for the optics to pick up, especially if you have good groups. Cool idea though ....
