Thread 'My HBN experience and process'Where can you get HBN.
I have looked and can't find it.
Thanks David
The bore will be very very rough to begin with. It is not coppering up due to how smooth it is. Mike, I do know what you are speaking of as I cast my own bore laps and make my own lapping compounds. bdeternv's barrel is pretty rough.No, the very last thing you would ever want to do to fix copper fouling is to polish a bore.
Use the blue J-B Non-Embedding Bore Cleaning Compound.
Then solve the issue with Tubb's FinalFinish, and coat bullets with Tungsten Disulfide (WS2).
This!Tubbs bullets will sure do some serious lapping of the bore and will for sure extend the amount of the leade, used as a last resort by me.
I'm not exactly sure, but I shot 5 minimum charge weight sighting in bullets, and 10 round ladder test. I did the standard barrel break in cleanings. Shoot-clean for first 5 shots then clean after 3 shots until ladder finished. The ladder showed relatively tight shot placement. I went back with 5 sets of 3 shot charges to check for a powder charge. I noticed that my groups were very erratic (i know that some will/should be…). I cleaned the rifle when I got home in my usual manner per Bore Tech's recommendations. I bought a bore scope because I wasn't sure what was going on, and I found this. Bore Tech Eliminator has always done great for me or I thought so at least, so I went back and scoped 4 other rifles of mine to verify my cleaning skills and found little copper fouling in them. Long story short, 30 shots with 8 cleanings focused on first 15 shots and 1 cleaning after 30 shots total. Btw, Bore Tech copper cleaner was absolutely useless against this copper. Eliminator cut more than the copper cleaner, but the best results of the three were the Montana X-Treme copper killer.How many rounds to get to this condition?
I switched from nylon to bronze brush a long time ago. Don't be afraid to use it - this is your most economical course of action since you already have a good list of solvents before going to a more aggressive route. Whatever solvent you use, A WORD OF CAUTION: READ THE INSTRUCTIONS CAREFULLY TO THE T, ESPECIALLY IF YOU SOAK IT IN AN EXTENDED AMOUNT OF TIME.
