Ok, I more (and different) info. The stolen gun was a 20, now he is shooting a Citori CX 12 with 30" barrels. It has only an adjustable comb and he is wanting to add adjustable butt plate. His dad said he has the comb all the way up and is shooting High.
Back in the day, about 40 years ago, which was the last time I set foot on a skeet range, we used 26" barrels, but now it seems longer is better. I gotta get out more.
He's not a big kid and I'm thinking that hoisting that Citori might be causing him not to be getting his cheek down where it needs to be. I don't know. I need to read up on it some more.
