david tubb told me to use sweets when I cleaned mine, when I started using hbn. I scrub with it and then follow up with hoppes #9 powder solvent to coat and protect the barrel.i do need to confess, I didnt clean my barrel till almost 500 rounds (6.5 cm) and it was still shooting great, just figured I better you know. ymmv but thats what I do. good luck with the hbn.What process do you use when cleaning a barrel that shoots HBN bullets.
Do you oil for long term sitting?
Do you oil or just the hoppes? Do you put HBN back in the barrel to sit?
