RE: Speed of sound question. Need to settle a debate.
I too think string jump is highly over rated. I've had one deer duck my arrow in 15 yrs of bowhunting. That old do was 20yds, facing straight on and watched me draw, I realeased and she ducked to the left and that arrow wizzed right on by.
Yes, it was a stupid shot, I was 13 and had only been hunting a few times with bow in hand.
