I toyed around with a 100 yard 22lr rifle for a while. I got a savage MKII fv that I could get to shoot 1.5" with one single kind of ammo. Using the Mil-dots on my scope for dope with a 50 yard zero, the first mil-dot down was dead on at 75, the second mil-dot was 100, third 125 yards. It was pretty much fun. I shot it this weekend some actually was was able to hit a 2" spinning steal target at 80 yards pretty much every time. I have a savage 93fv in 17hmr that shoots about like the pictures posted above as well.
