Hello, much to my dismay my new to me 10/63 barrel is a total disaster. Rifling is atrocious...missing, or corroded. Pitting and gouges in the bore. It somehow stabilizes bullets, but accuracy is 10+ MOA. Does anyone know of a reputable company or individual who can take a complete rifle and a new drilled/threaded/extractor cut barrel and do a rebarrel (complete de and repopulation, headspacing and all that)? Thanks.
