Take note of my previous comments on Colt gutter sights. These guns are plenty accurate in and of themselves, but these sights are not what you want if you're trying to chase down the smallest possible groups, especially at a distance. That said, given the right light, they're still very useable.
Here's a long range attempt (30 yards) with the Cattleman 22 LR. Had a good group going until I pulled a couple. Good enough, though, to show me these guns can shoot.

By the way, I regulated these Colts to shoot point of aim, not for a six o'clock hold. A six o'clock is superior for bullseye work, but for field work and plinking with fixed sights like these, I much prefer a dead on hold. More traditional, too.
