RE: barrel break in??
<font size=4>IMO,Break-in,for a new factory barrel,must start with a cleaning of the bore,before firing the first round thru it.The barrel will have dirt and grit in it,from the factory.This is about as abrasive as you can get!Then,do your break-in thing,with it?
As to the JB type of bore cleaners,I ruined 2 barrels with the stuff!What you don't expect,is that each stroke of the cleaner,is taking a part of the throat from the barrel.I cleaned the throats out of the 2 barrels,i mentioned!1 was a Douglas and the other was a factory Remington.
Stainless steel is softer than Chrome-moly steel barrels.
I agree,with the idea of soaking a barrel with solvent,waiting and then patching it out.Doing this,until it is showing little or no dis-colored patches.
The old saying"Haste,makes waste",is true,when cleaning you rifle barrels.IMHO.
