I' ve shot walking deer inside 20 yards with no problem.

Shot one walking at 30 yards and hit high and 3" back from where I wanted to. Fortunately I hit an artery and he died within 20 yards. I will NEVER take that shot again. It was really, really stupid.

My limitations are inside 20 yards I' ll shoot them walking. Outside 20 and inside 30 I' ll bleat them to stop and shoot only if they stop. I will never shoot outside 35, too many variables not in my favor to get a clean kill. That boy better be standing still, not alert for a minute, and without any wind before I think of a 35 yarder.
