Ahh yes to straight
To straighten a barrel yes I would agree. But in today's modern age of CNC machining and other machining processes it would be difficult to NOT create a straight barrel. A rifle and a shotgun are entirely two different animals. The shotgun is a short range firearm. Think about it for a minute. If you bend a rifle barrel to make it out of straightness and sight it in at say 50 yards. At 100 yards it will be way off because the bend was set at the 50 yard range. This is the reason double rifles are regulated for a specific yardage. At some point beyond that yardage the bullets will cross paths and get further away from each other the farther the yardage.It is very possible your barrel WASN’T made exactly right in the first place.
Manufacturers set tolerances for straightness and bore centering.
Mauser, Sharps, and other famous makers had barrel straightening equipment that were used on a daily basis. I would imagine it is still a common practice for modern manufacturers.
You would be surprised how little flexing it actually takes to change POI a small amount .
I have never straightened a rifle barrel, but I have done it to several shotgun barrels to move the center of the pattern, Easy to do.
I would not hesitate to do it to one of my own rifles if it needed it.
