RE: Speed is all you need! (?)
CBM SC,
I have stood in Archery Shops and been at 3-D shoots and heard the " quiet" 300+ fps bows that shooters bragged about. In reality they were far from quiet. Compare them to the quiet thud of a good longbow and they are " NOISEY" !!
Your shot at the buck was at the extreme end of the range at which deer will drop at the release of the arrow. I suspect yours tried to drop as he heard the arrow whistling as it zipped towards him. They definitely can drop to jump quicker than the arrow can get to them if they are within the 30 yard range.
And no, they don' t dig in, they drop, about 1 foot to jump when they hear a sound that they cannot identify and are within the roughly 17 to 30 yard range their first reaction is to drop. Of course, that is a general statement, but is far too often the case.
