I'll start by admitting that I think I'm the limiting factor in most of my shooting. I think most of my rifles are mechanically capable of better accuracy than I'm capable of wringing out of them. For example, I've said that my 10/22 is MOSC (Minute of Soup Can), but the truth is that for many years, I never really tried to measure accuracy. If I could hit the soup cans, I was happy. In particular, I really only started to try to push myself on The Making of Small Groups a few months back. And as I just put a new stock on my 10/22 and bought a bipod, I'd like to set it up and really see what I can do with it.
And with all of that said, this is my best target to date. Compared to some of the shooters here, it's nothing to write home about, and I know that. However, it was pretty good for me. Ruger American Rimfire Target with Norma Tac-22. (At least, I think it was Tac-22. I know it was Norma.) The center is 1/5", and this is 10 rounds at 50 yards.
