Im new to guns and i just bought a mossberg 590 and it has a all purpose barrel, do i have to break in my barrel even if it doesn't have any rifling?

@Liberty4Ever My new favorite bore cleaner is Bore Tech Eliminator. It's as good as any carbon fouling solvent AND as good as any copper fouling ammonia solution, without the solvent or ammonia smells. It's odorless and nonvolatile, so I can use it indoors. The Bore Tech brushes don't have exposed copper so they don't produce phantom blue indications on patches so you can tell when you're finished removing copper fouling.

But I'm not an EXPERT gunsmith. :-)

I clean bores with an Otis cable, pulling a patch wrapped around a nylon brush. If needed, pull just a brush to get deeper into the rifling grooves. Always pull from chamber to muzzle and there's no chance of damage that can occur from the flex on a pushed rod. It's a lot cheaper and easier, too.

Howa recommends the clean, shoot a round, repeat break-in technique, but instead of oil, they use Windex to completely remove all oil so the copper jacket burnishes the steel lands.

Good stuff...thanks guys.

Very interesting videos! I will surely do this if Santa brings me that Henry pump action octagon I told him I wanted.

Cleaning copper fouling out of a bore is hard work and unless you get all of it out, you're simply laying fouling on top of fouling, not polishing the bore. Try this, use a cheap copper solvent and when your patch is no longer blue/green, try Sweets 762 and you'll probably get another blue/green patch. When youre done messing with that, try a Foul Out and see if you still have copper in your bore. Probably will. Good luck getting all of the jacket fouling out with a few patches at the range.

Sorry, but I think this barrel "break in" stuff is nonsense.

The bullet wears steel very little. Unless the imperfections are very tiny, the bullet is not going to wear them down. Excess copper fouling can be caused by a rough bore, no doubt. The smoother the bore, the less fouling. However, unless you have a very expensive hand lapped custom barrel to begin with, you're probably wasting your time.

A dull factory reamer is going to leave marks in the throat that a bullet will not remove.
