I'll let an expert answer it with more intricacy especially about stock design and recoil, but these doubles are designed to place your eyes directly with the open sights.

You may know the below anyway but some visitors may not.

Trap shotguns purposely are designed to raise your head and sight picture. As a clay target travels away from you in a rising manner the trap shooter can see the clay follow it and fire. All while the clay is in sight. The gun is designed to shoot slightly higher than the "point of aim". This means while you are pointing or "aiming" at the clay the gun is actually pointing in front of the clay.

With a field shotgun like I use for trap when I occasionally shot it, I must actually 'cover' the target with the shotgun as the sights and point of the gun are roughly the same.

American style stocked bolt actions are now all designed fro scope use and raise the head for a scope. A lot of European stocked bolts are still designed for open sights so the head is unsupported when using a scope especially using high rings for larger scopes.
