On a side note. I would really like to know just how the pros remark barrels that have been converted by lining, or say sever shortening. First how do the remove the original marking. They must couture sand them off. You could fill them by tig welding, but I would worry about weld distortion on a thin barrel. Then restamping. It is pretty difficult to perfectly align and evenly strike individual stamps. I etch my mark in blades when I make custom knives and it would take much to get and use a stencil to make a nice mark in that way. I already have a nice etching setup.
