I have never shot a deer in the neck, but wondered if anyone has? I also do not use mechanical heads, but I read that many of you out there do. Since you can get about 2.5 inches of cut out of many heads, it just seems to me that a well placed neck shot should be deadly. another reason I ask this, is that on many of the BHOD web shows, the shots have resulted in non pass through kills. If the huge heads do so much damage, would a neck shot make a quick kill, and wouldn't the blood trail be heavy? Final reason for asking is those pesky head on situation, seems to me that white spot under the chin would be a great target when you have a clear shot at it.
