With a good spot weld and proper wing shooting your cheek will necessarily be on the stoc or you will shoot high. And it will bust up your cheek after a good shooting day in the field.

I used to shoot doves on a familys farm. The were big quail hunters and shot skeet regularly. Dad and two sons used to go to Mexico every year to shoot whitewings. 4 guns apiece, a loader and a boy to fetch the birds. When they got back their whole right side looked like someone beat them with a baseball bat.
Makes me want to take off and go right now!
