Not to chime in here... but at 800 yards (and what you are proposing - I
have a very good idea what you're shooting based on what you've stated)...
there should only be one hole.
I have some friends that shoot .308 to 20mm - and larger (although the .338
Lapua gets special attention) and may come up with some suggestions... let
me do some digging.

Hi
If you put enough shots through the same area, there's nothing left to
show a hole.

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 ....

Why not using optical methods for shot grouping?
A cheap web camera with equally cheap telescopic lense can resolve 1mm.
Some image processing software can find shot positions within the 1kx1k
pixel bitmap.... etc..
