    I have been using different brands of HBN with great success, finally settling on Tubb’s formulation. I am not a competition shooter so have no need to keep bore coated until the next days event. My question is how often to you clean your bore after shooting coated hbn bullets for the day and what do you use to get the coating out of bore? I usually only use Bore Tech Eliminator with patches and nothing else. Thanks for any input! This is new to me...

    Its hard to get that stuff out once its in there. Youre going to have to use a bronze brush or youre going to have 2 things building up. Back when people were trying it they used kroil on a bronze brush to stay on top of it.

    I used HBN in all my rifles for a while and just cleaned it with solvents and brushes till the barrel was clean after every comp/range day.

    All my rifles but one it wasn't to much work to clean but my 6 SLR I shot HBN in the barrel from day one and the barrel took forever to clean.
    I figured I just had a barrel that loved to carbon up and mix in a overbore caliber burning a case full of N160 it was what it was, it would clean and then I would discover another layer of carbon and id clean that out and there would be another layer. It was almost as if I had layers of carbon protected by something where I had to break through the barrier to get to the carbon.

    Fast forward 700 rounds and I decided to try a new bullet but deiced to run them clean, to my amazement now all of a sudden the barrel cleans up so fast I have to go in and double check to make sure its clean, I get a little bit of copper now but it cleans up like nothing but those "hard layers" of what ever I had while using HBN is gone.

    To get back to your answer, like dusty I would suggest getting some decent broze brushes

    If you don't already own one, I'd suggest buying an endoscope camera like the Teslong or a good borescope. Either will answer your questions about effectiveness of your cleaning procedures. I've used endo cameras for decades, but not until the Teslong borescope camera came along did I have a really clear view of what's going on inside the barrel, from throat to muzzle. It was a very enlightening moment, no pun intended.

    So is hbn old news now or does it still have a practical application?

    I've got a couple of shooting friends that have shot BR for many years and have used Moly or hBN. They tell me hBN is the best of the two. However, they stopped using either when they bought their latest barrels. That's stopped me from trying it.

    I've used HBN for 6 out of my 7 years in competition. I only clean after each agg. I've never seen a build up of the stuff and I don't use a brush whatsoever. Just a couple of patches of Wipe-out and that is it. Never had a carbon ring build up in any of my barrels. The only thing I can say about the stuff is that it makes barrel cleanup a lot easier. The only time it started to copper up is when the barrel started to go south on me and then I screw on a new one. Barrels are disposable.

    Dusty. Quite a few of my fellow competitors in SR score use either HBN or WS2.

    Dusty you are right, to expand on this a little. when the coating bullets/barrels started the rage was lock ease man next thing to sliced bread you'll never have to run a brush in barrel ever again. well that didn't work. then came moly same thing man barrels are going to last forever never clean again then it was well minimal cleaning, well that didn't work. then we went to danzac wow this was going to be better then moly its less messy you can shoot a agg and not clean, well that didn't work. finally the HBN call me a skeptic I have tried it but still had to clean didn't make barrels any more accurate or last longer so whats the point... the only ones that want coatings in barrels are barrel makers and gunsmiths they get more work.....

    I have been using neolube. Don’t know if it’s the same. What I can say is that it takes feeer shots for the barrel to settle down.
