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

[Heathkid]

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.
