I discussed this with Matt/PA a few days ago, and I'm running into this full force. Where the heck does that block come from? I can put an arrow into the kill zone of my 3D deer target ALMOST every time at 10-15 yards. ALMOST 'cause I'm still learning. At 20 yards, it all changes, and I miss the entire stupid deer or get a nasty gut shot or neck shot as often as I hit the kill zone. What causes the mental block? Any ideas?
