RE: Confidence lost....
Get your ANCHOR Point set at 15 yrds. Nothing wrong with a 15yrd pin. Then work your way out. I find if your bow is tuned and your shooting bad, your anchor point is moving. Just a little change on each shot makes a big dif out at the target.
When you hunt and you first get situated in your stand, mentally think about the shot. Walk through the smooth draw, Anchor point, and follow through.
Take your time. You still have 1 month before bow hunting is at it's best.
