I don't know that that's necessarily NOT a good thing. I'm sure the arrow in their slapping and flopping might cause some deer along the way to take and extra spurt in his flight, but probably not. What that arrow hanging out both sides would do is work on the holes to keep them open and probably allow more blood to get to the ground. IF the arrow penetrates both sides in the beginning, as far as I'm concerned you're good to go with a blood trail. I would think it's a matter of time before one doesn't go all the way through though. The 8 point I shot this year the arrow passed through and stuck in root system below ground level of a maple. I worked up a sweat getting it out.
