I 'm well aware of stock adjustment .My son was Florida State sub Jr and Jr in ATA. But that has no effect on where the barrel shoots . Only the site plane will adjust the pattern to where the barrel is pointing If you cant adjust the site plane you have to adjust the barrel. Assuming Big word if he is using the rib and the front sight or the front site and a small middle bead and the gun is shooting high left. Any place you put the stock it still will hit the same spot. LarryKMart said:I am quite aware of the different types of shotguns. I competed in ATA Trapshooting for over 30 years and even managed to make the Trap and Field All American team one year. My tournament guns have the ability to be adjusted every way known to man, including an adjustable rib.
I CAN make the front bead and mid bead line up making the correct adjustments on the stocks..
Maybe you can't.
