I am hunting squirrels with my 10mm again and I am not getting the shots. I had 2 withinrange (very close)but they never stopped. I can't make a headshot on a moving squirrel. Does whistling stop them like it does deer,or will that just educate them to the fact that I am right on top of them? Yes, I know there are better squirrel guns, I hunt everything with my 10mm. It forces me to improve my skills.
