i have a used broughton barrel that i have been cleaning.about 150 rounds,
i am using motana bore cleaner and cooper cleaner.
soak patch with bore cleaner, let sit 30-40 strokes with brush, wet patch, patch will be black,
now i have repeated this cycle 20 times and the patch always comes out very black
Question, what am i doing wrong, or need to do, never had this issue before.
am i wearing out the barrel....
Order some BoreTech CU+2. You have a very fouled barrel, probably both copper and powder. I didn't have good results with the MT extreme. Also I would not brush so much, just patch and maybe brush once or twice a session. Another thought is, if the brush is brass you might be pulling color off of it, but that should be blue. I use nickel coated jags too.
I agree with above, get either some bore tech eliminator or bore tech CU+2. These are the best solvents I have ever used and they won't hurt the barrell. Just make sure to use something other than a brass jag, the solvent will turn the patch a blue green color. I use a nylon jag that works pretty good
