There have been many post about straight barrel and testing them before starting a project. Before the shooting world saw many improvements in machining and tooling, most barrels had to be straightened after boring and rifling.
Here are some of the old tools and methods required to end up with a straight barrel. I saw one of these early barrel straighteners and was fascinated by the skill of the Gunsmith and the fact that this process required true north light. The tool had a large hand wheel that applied forced in the center of the bend of the barrel between two points and the gunsmith looked down the bore and had to judge how far past straight he had to go to allow for the barrel to spring back to be straight.
We are very fortunate to have the quality of present day barrel makers and with a little testing we can find a near perfectly straight barrel.
The link below shows some of the tool that were used and a barrel straightener that was used and one of the best of them.
