The most nervous I have been when shooting a ML was when I sailed 5 bullets through my chrony @ 100 yds

I haven't worked up the nerve to do it yet.
Why do it at 100 yards? If you can do it at 10 feet and have +-20 fps? The medium (air) is pretty uniform from 0 to 100 yards. I can understand your nervious, you would want a pretty tight group to go shootin' thru it at 100!
