I know, ever since I started shooting around 1965 or so, I bet I have easily shot over a million rounds.
With that being said, I typically do not shoot more than a few hundred rounds per year from any of my guns. I doubt very much that any of my guns have ever seen 1,000 rounds shot in one year, even on a gun that I shoot often.
Once a gun is sighted in for me, or I have an accurate load developed, I typically only shoot if there is something to shoot at (a varmint, a nuisance skunk--which we have a LOT of, an occasional coyote, etc.).
So, since I don't shoot all that much compared to a lot of you folks, I don't keep any record of rounds shot.
