I have a Rem 870 12 ga that I mainly use for bird hunting, but every year a couple of months before bird season I take it to the skeet range and shoot a box or two with it each week. Even with an extended stock and a Limbsaver pad that match my competition Trap and skeet guns, the recoil of that 870 was bothering me and bruising my cheek.
I then installed a mechanical recoil reducer in the stock and that took the bite out of that gun.
