As many have said, there is a lot of good information above, ill be repeating some of it.
My guess is you are aiming and not pointing. As someone who shoots a lot of rifles and pistols, it was odd for me to get used to the idea that I should only use the beads when mounting the shotgun and not when trying to hit the clay. You need your mount to be the same every time so that your sight picture is the same. Always focus hard on the target, and understand that your eye is the gun's rear sight (unlike with a pistol or rifle). When I was aiming the bead I would get poor scores, vs point and focusing on the target id get an easy 5-10 more clays per game.
Other things i'd consider thinking about.
- Practice your mount at home until it's the same almost every time. Close your eyes and mount the gun. Is it aligned correctly? If not, maybe improve your fit if you have an adjustable comb. Remember to bring the gun to your check and then shoulder, not to shoulder first and then lean your head over.
- Focus on pointing with focus on the target, not aiming the bead
- Shoot with both eyes open
- I changed this years ago for pistols and shotguns, which greatly helped. It will be odd at first, but will pay off longer term. But I also know many shooters that do well with 1 eyed shooting.
- Figure out the POI of your gun. Is it flat, high, etc? This can help with understanding how the sight picture is
- Try moving was shooting slightly left of my aim when I took the gun out to test the POI
- Separate Practice vs Competition/Implementation
- Practicing, you try things, Competition you just do what you practiced and don't change it
- Learn the hold points from each station to have the best movements possible from each station to the target.
- Practice a solo game only on Station 5, and have them lock it hard right if they can/will/
