When I got my scope (same one) I immediately checked all if my rifles. Nothing great to report until I got to my Rem 788 in 223 rem. The bore looks just terrible. I scrubbed and cleaned the heck out of it and the gun quit grouping. I quickly found out the gun needs a fouled bore to shoot accurately. As some one mentioned before do not go by just the appearance of the bore. The 788 shoots under 1" if I do my part, but If I have cleaned it I need three fouling shots to set things right.
Sometimes it is better to not know what a barrel looks like as long as it shoots.
