Steel has a memory, and can often be bent right back to where it started.
I’ve seen the photos and the fixtures for truing barrels, but, it was in Europe, not here.
Part of the installation of every poly choke or Cutts compensator was the “straightening “ of the barrel, actually installing a bend in it to move the pattern upward. Simply removing the choke device often results in a gun that doesn’t shoot where you look.
Guys here have posted about their attempts at correcting double guns by slamming the barrels in a door, or, bending in the fork of a tree.
Not much lately, thankfully.
Best,
Ted
