Nowadays, I'm happy hanging out in the woods and dropping one or two per hunt. I think that I've killed about 6, all with a .17hmr. However, far fewer people are hunting squirrels in my area than in the past, and there are lots of 'em. If I wanted to do a serious hunt, I could likely limit out every time. When I was younger, it was mostly greys, then the reds started taking over. Not it seems like the greys are back in greater numbers now. The season starts August 1 in Illinois, which I think is way too early, unless you are comfortable killing she squirrels with signs that they are still nursing young.
