I have a Hern barrel with a dom liner, after installing a vent liner I was cleaning the drill chips out. After My first realy good look down the bore I realized that it has a dog leg. I couldn't beleve it so I looked with a stright edge and it curves to the right. At mid point it looks to be out about 1/8" , up and down seems to be stright. Has anyone else had this happen with them?
