[QUOTE="Bob Wright, post: 2896626, member: 104363"] Then stay with the Montana cleaner and phosphorous bronze brushes. You might also lap with JB products just to attempt a quicker break-in. Where premium aftermarket barrels are honed for size after gun drill and ream, yours probably had minimal honing if any. That is going to leave reamer feed marks (think internal threads on a nut) you're going to have to smooth out by shooting and cleaning until the barrel complies with your wishes. Secondly, copper likes copper, meaning you're going to deposit a lot of jacket copper over bore copper deposits. It just gets worse without stripping it bare with your cleaning. You can see the flaky copper on your lands that are co-deposits, layer on layer in my opinion. You might contact Begara to see if this is a warranty item. Give them a round count, cleaning count, etc. It's not a normal thing to have copper build this much. I've never seen it on factory or higher end barrels. [/QUOTE]
