Back in the 70s my dad (a John Deere dealer) bought a new contraption made to run deer off your property...We raised mainly corn, soybeans, peanuts and wheat and I could ride around and count 150 deer in just a couple of hours...

This rig had a propane gas cylinder, a car battery, some wiring and a megaphone with a spark plug in one end...You could set it to go off at different intervals...The gas would be released and the plug sparked and BOOM!!!

We sold a few dozen within 2 weeks they started coming back the dang deer were feeding all around them...

I have shot many deer off a combine or a tractor, sighted in rifles in the middle of the day and killed deer that afternoon...

I would use a little common sense and stop shooting a month or so before the season comes in, but I always have guest check their zero before I let them hunt and it is done on one of our farms, often before we hunt that farm...
