I read a test in G&A of a scope which can take ten seconds of digital picture while aiming and shooting. It was field-tested in a coyote hunt. The writer was quite pleased that a review of the video showed that what he thought was a miss was actually a hit, and he went and found the coyote.
I disremember the brand name, however, so you'd have to go to G&A or do the Google thing. But it ain't cheap.
