Look at the original Ruger 77 stocks.
The one everyone thinks is great. It does look nice.
Don't copy it.
Hardest kicking guns I've ever shot.

Stock fit is very key to reducing recoil in shotguns and rifles. The pitch on a shotgun stock will make a big difference in how high the muzzle rises (which leads to being hit in the face). There is a Youtube video of one of the guys on the Army Shotgun shooting team showing how to fix this.
