Greg,
My target panic started because when I switched from a compound to a trad bow, I was over bowed, but I didn't want to admit it.
I began to short draw and I wanted a consistent group SO bad that I released when it felt right.
My groups weren't too bad, just very inconsistent due to my unreliable anchor point.
Someone here, (I can't remember who but many thanks) told me "you don't HAVE to release!
It was great advice. When I shoot, every couple of arrows or so, I come to a complete full draw, pause, and let down. It may be 3 in a row, every other arrow, I don't know and just let it happen, sometimes I shoot, sometimes I just come to a good solid anchor, hold, hold a little more and slowly let down.
Then I may shoot an arrow or two.
I also only practice with one arrow.
I shoot, pull it, walk back to my shooting range, and shoot that one arrow again.
I also started all over again by shooting very close, with no target and thinking about FORM!
Another advantage of shooting only one arrow at a time at no target is you have no target!
When I shot more than one arrow into a blind bale, I had the habit of trying to shoot the nock of the first arrow! In other words, my first arrow became my target, or concentration point, and my form became secondary and the short draw and panic came back because I wanted to group arrows and hit that nock so bad!
Hope this helps a little, and good luck!
I'm sure you'll beat it!
John
