i approach from the rear.....tap its rear...then if nothing happens i go up and poke its eye with the tip of my barrel....if it blinks you got some more work to do.......never had it happen.....and dont want to......but if it gets up while your walking from the rear you have a really good chance to put it down....i keep my rifle ready and loaded and am always thinking of where it may take off to and plan shooting lanes almost.....i rather be safe and take my time then have a deer run off that i should have put down......
