Losing sight of the target behind the barrel. Don't try to keep your barrel ahead of the target the instant it leaves the trap, because the barrel will be blocking your view of the target . Let it get out where you can see it
clearly than move the gun through the target and release the trigger.
Few days ago IIRC, you were talking about holding a higher gun. When I have a day I can't hit a barn from inside I go back to basics and start again. Foot position, Gun mount, Hold point, Focus, Grip, all those tiny things that can get out of kilter and cause a lost bird.
Were you struggling on station 1 before this? Target panic?
Go to a trapfield and shoot 3-4 boxes on station one and prove to yourself that you want to attack station 1, not defend against it. Play with your hold point and view point till you feel comfy. Smooth is good. Out of control, fast, bad.
I ended up using the "hold out 1 foot, and level with the front of the trap house roof" approach. Can now see those pesky left handers that cost me so many lost targets. I even used to flinch (throw the gun at them) with my release, because I wouldn't see the left hander quickly. Also, I "Look" out with a soft focus. Seemed to help me.
Are you wearing a heavyer clothing then normal? When I switch from my lighter sweat shirt to my heavy winter coat,I had the same problems.Had an adjustable butt plate installed and hade the l.o.p. shortend by a 1/4". Turn it out in the warm weather one turn,and in one turn for winter shooting.Helps me to keep my head on the stock. Just an idea that worked for me. Ray
