When they pull a button through a barrel to form rifling, is any metal removed? My understanding is that the metal is displaced not removed. OSR is the displacement of metal. As a barrel ages and is fired many times does the steel work harden. I think ribs coming loose and loss of regulation is a bigger problem with the older mono bullets than osr. What does JJ have to say about this ,He's done more repair work on new and old doubles than any one else.

At least there is a public statement by Barnes now, if you were to have a problem, It would be much easier to recover any losses in court or via a insurance claim. They are missing the boat by not resolving this, they would expand their customer base and take a large share of the market that wooleigh has had wrapped up for years.
