[QUOTE="Wyowind, post: 2896736, member: 67305"] I have seen a number of Remington rifles where the chamber and the barrel were clearly not aligned. With a bore scope it was possible to see where the lands started on the receiver end of the barrel. Looking over 360 degrees, you could see lands on one side but none on the other until some little distance down the barrel. Surprisingly this did not necessarily have adverse effects on accuracy, at least on a hunting rifle. It might be a different story on a target rifle where expectations would be higher. One rifle was far enough off that Remington factory ammunition was giving high pressure signs. The bullet was having to straighten out after entering the barrel in a crooked fashion that was not in line with the center of the bore. I do not know how Remington made their barrels and chambered them. But clearly it was possible for the barrel and the chamber to be mis-aligned. Remington, and others, did not regard this as a fault unless the accuracy was outside their specs. WyoWind [/QUOTE]
