Gun Fit and Cheek Pressure
We have learned a lot about gun fit and cheek pressure over the past 25 years as professional coaches, the previous 17 years as competitive skeet shooters, and then as sporting clays competitors since 1983.
We also have heard the theories about the iris sitting on the rib like a marble on a table. But we have found what works for us and all of our students. With the iris in the above position, whatever cheek pressure is required the gun will pattern high left for right-handers and opposite for lefties.
If you look down the barrel, you will be looking down on the rib. This will make the gun shoot high.
