While I am not that proficient with the bore scope Ill still say with a good deal of confidence that the build up of what I think others may relate to if I may suggest looks like teflon coating. Whatever this build up is Has inhibited me from getting a good look at the actual steel in the bore. With each succession of 10 rounds the build up seemed to cover more and more of the bore. Prior to starting this process my experience with copper build up was in the last 4 to 6" of the bore, that is near the muzzle. With the Tubbs final finish this was closer to the exact opposite.
In their instructions they are very adimate about the customer needs to be very meticulous about achieving a clean bore at the start & prior to moving on to the next series of 10 bullets. The instructions suggest using a brass bore brush one size larger along with a good copper cleaner like a couple prominent names of copper removal products. I did achieve a very clean bore at the start & through steps one through three. In excess of 300 passes of a brass brush with my choice of cleaners were required to remove all of the copper after each series.
I have been using the bronze brush from the start to step three. I am hoping to not use the bronze brush on the last two steps & that remains to be seen as to what is required. I have finished the 4th firing series and have been cleaning this time around only with patches and copper removal solutions thus far. To tell the truth I am not optimistic on achieving a clean bore without the bronze brush at this point.
At this point the bore is nearly entirely coated with the secondary residue that I was not expecting along with a great deal of copper.
the secondary residue started to build the most near the muzzle and progressively built up to the rear with each series of 10 bullets. So the secondary residue is preventing a god look at the bore. Until I reach out to the company I have little or no Idea as to weather the secondary residue is expected or not.
