I just finished a new build and have a 300 WSM with a new Bartlein barrel. Looking for advice on bore treatments prior to shooting this the first time. I have some Bore Coat and a friend is advising some treatments from Tetra Gun. Anyone with experience with these products and your thoughts on the efficacy of such treatments.
I would recommend you follow Bartlein's recommended barrel breakin procedure: Bartlein Barrels, Inc. - Break In/Cleaning
Dyna-Bore coat is one I've been reading up on. I have not used it yet, but it sounds like a good option.
+1.....As Bartlein says, it is the throat you are breaking in. (usually burrs where the lands were cut).......Rich
