What would be involved in re barreling a Win 70 SS Classic in .338 to .375 H+H ? The .338 barrel was a mess new from the factory.Hack and tool chatter on the lands.Fire lapped helped somewhat but will still copper foul every 20 shots or so.Sent back to the USA to Win after much hassle came back 8 months latter claiming it meets their accuracy standards.I phoned and asked what that was but they wouldn't answer.I will either handlap it from here or rebarrel haven't decided.........Harold
