Took delivery of my grandfather's Remington 11-48 this afternoon. He bought it in the early 60s, and used it until he stopped hunting in 2000. It is a 12 gauge with the 28 inch, full choked, plain barrel. He used to use an old Weaver scope from one of his .22s on an Echo quick release mount (on the L\H side of the receiver. Left the scope with the Winchester 67 and the Springfield it's on now.) during deer season. The way he would check zero was to set up 5 bottles in front of a berm, walk 50 yards back, prone out, and bust the bottles. He would then do it sitting, rested, and off hand on 5 more bottles. If it took him more than 10 slugs on 10 bottles something was wrong. I only saw him miss during this once in the 7 years dad and I hunted with him. One of the Q\R set screws was loose. tightened it up, and no more problems. Some pictures.
