I shot a crow off a fence post from 220 paces with a Ruger mark 1 ,22 auto pistol. One shot. Iron sights. dead crow. Killed many cottontails on the run from in front of my beagles with various .22 rifles over the years. A good high school buddy and I were sitting on the bank of a local farm pond fishing for bullheads one afternoon. Naturally we had our .22 rifles along. Lots of birds flying over head all afternoon and the fishing was a bit slow. Finally I said "betcha I can whack one of those birds out of the air with my .22". Pulled up bam, poof, feathers floating on the breeze, dead bird plops in the pond.
