[time-nuts] A real world project need for timing accuracy...

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 ....
