Yes it is funny how they seem to know what is dangerous to them. I set up my spinners at about 60 yards and was shooting at them with my 22 caliber Sumatra when 2 bucks and 2 does wandered across our field about 20 yards behind my spinners, they stopped and started to eat while I carried on shooting. To my dismay they just looked up for a second and then continued to eat as the pellets smacked the spinners, they still did not run and eventually just strolled of up the hillside behind the spinners. Luckily for them I am no hunter, as the bucks both had some good sized racks on them, Neil.
