So I have a backyard incognito setup dreamtac .177 tuned for 10fpe so 9.57gr at 700fps. Shooting is usually 30 yards and under mainly 20 yards. This setup is perfect can take anything from squirrel and under. Its so good I am not getting pass throughs even on broadside mice. With that said my question is on the smaller critters lets say chipmunk and under so rats, mice, chipmunk etc is a body shot better? I have learned today that because its so accurate and so small in size I found I just missed the lights out switch on a chipper and hit just below the brain. The mice and rat were good shots but again not sure if straight up vitals is best.
