Agree with not changing it to 06, just looked closer and can see it would be a major project. Was able to remove rust from barrel, surprised to see no pitting. Now considering replacing barrel with a used pre 64 barrel from pre64winchester.com or just refinishing existing barrel. ultimate would be to find a 358win original barrel but doubt that would be feasible. Could re-barrel to 358 or 338fed but would prefer to keep it original.
