I shot a doe at 17 yards on Saturday, had a complete pass thru and the deer didn't even move until the arrow clanked the ground behind her. The other two deer that were in and this one only moved about five yards and stood there. My bow is extremely quiet compared to many I have heard so I am going out on a limb here and saying the bow is probably making a lot of noise during the shot. Were the deer spooked at all when they came in? They will jump at every little crack if that is the case.
