Went sighting guns for all seasons. Started with 22LR, 22Mag., 270, 50 cal. muzzleloader, and finally shotgun. Shot 4 boxes of rifled slugs in a wood-stocked 870 with regular pad yesterday, getting ready for a whitetail hunt. Oh My God, it hurts!!!!!!! Talk about black and blue shoulder. It really needs the new one before I shoot that much again. I believe it is one of the best improvements you can make to your gun.
