Well, as long as we're going to do this I might as well put in my two cents worth on the deer taking the step. If you mind your P's and Q's and pay attention you can pretty much figure what step he'll make next. Arrow flight time from 30 to 60 yards isn't all that much different. If my arrow is traveling at a moderate 265 feet per second it doesn't take a genius to figure out it's only in the air another third of a second from 30 to 60 yards. Secondly, it's been my experience over the last 34 years of bowhunting that a deer at 20 yards is more skiddish at the sound of a bow going off than one at 30 or 40. The further removed from the sound the less they react. They may throw their head up and look, but they don't squat and bolt like they do at 15-20. It's all a trade off. The only real problem is finding a clear shooting lane and being able to make the shot with a good broadhead. I wouldn't feel comfortable with a 50 yard shot in my whitetail woods... but put me out west in big sky country and I'd be shooting. 60???? beyond my capabilities(in my mind anyway) I loose any semblance of range estimation once you start pushing 40... that's the big problem, not the deer taking a step. If you got the range down or time to range... well that's a different story... say like hunting on an open field. I know an old Pro shooter in Georgia that whacks deer at horrendous ranges with a bow.... but that's him. I wouldn't think of it. I have no idea how many he misses or wounds... probably no more than me.
