The Dirty Little Secret of Gun Cleaning
A gunsmith who’s cleaned thousands of gun barrels reveals what so many shooters do wrong—and make their rifles shoot badly.

From the other brother over on the other forum...
Well, actually...I am running a little short of patience by now!
The rifle build turned out beautiful... Naturally, that would be the one that gives me fits!
3 scopes, 2 stocks, 6 powders, 5 bullets and 3 primers and won't dip under 1 moa and stay there.
Will try some flat base bullets tomorrow.
If it doesn't get under 1 MOA and stay there... I'll contact Bartlein.
You know the old saying, "if it ain't broke-don't fix it. I got a couple of guns that look the same way. As long as accuracy isn't off, leave it alone. My 2 cents.My accuracy isn't effected by it, however, with borescope it definitely isn't "clean".
When I got my Browning AB3 in 300 WM it took over 200 rounds for it to quit shaving copper and for the black just like you described to come clean. I'm not sure since I did not bore scope it before firing it, but some of the bluing that they use outside the barrel may have leaked in during its application to the barrel. After all that was done it holds about .75 MOA or less depending on the round fired. It definitely likes 180 gr Nosler accubond and IMR4350.My accuracy isn't effected by it, however, with borescope it definitely isn't "clean".
I would definitely try Hammers before sending it back to Bartlein…No sir... I have not.
I've been reading excellent reviews about them though.
How do you know this to be true?DON'T PULL ANY BRISTLE BRUSH BACK THROUGH THE MUZZLE. REMOVE IT BEFORE YOU PULL THE ROD BACK then reattach, repeat as needed to loosen fouling.
Wow, looks like this barrel could use some J-B bore compound!My Bartlein is the same, 450 rounds. I used CLR and a plastic brush to deep clean a few weeks ago. Groups instantly tightened up to 1/2 moa but I still had the carbon layer. Bore paste might get rid of it but I'm not using that stuff on this barrel.
