Nobody has said that the technique is any different between sighting in a shotgun and a rifle. What was said is that a gun should be pressed into the shoulder crease and you should have a decent hold on the front forearm area so the gun doesn't jump and basicly moves to the rear. You also shouldn't hold your breath when you shoot. You should be taking a nice breath as you are ready to squeeze the trigger and then gently let out the air as you do. Maybe you don't realize it and you're flinching due to the recoil of the shotgun and you don't when you shoot the .308. Who knows! Something else that hasn't been touched on is that when you bench rest a gun the forearm of the gun should be what is supported by a bag, etc. and not the barrel itself.
