Smokin,I'll give you an example of sorts.I had a 16ft.x 2inch piece of rough cut poplar wood for stairway in an old barn.Stringer for stairs. I cut the notches in it for the risers and treads of the stairs. The board was straight but when I cut the side for the risers and treads the board "bowed" in that direction. The board wasn't stress relieved since it was not dried. Well just like that wood a pistol barrel of non-stress relieved metal will bow in the direction of the dovetail cut.Walaa, a slight bulge inside the barrel. Know what I mean?
