The Majority on this web site cling to JB's coat tails because they have no opinion of their own thinking she is a goddess of some sort, BARREL BREAK-IN does help in some cases, some claim there can be barrel damage done with break-in are idiots that dont use a rod guide.
Use a rod guide, bore tech eliminator and you will notice a positive difference doing a barrel break-in
And you notice this difference with the same rifle?
BTW, what you said above about JB is Horseschitt with a capital H. People respect his opinions because he puts in the work to really understand the science behind things like "barrel break-in" and he knows what he's talking about.
