I clean my guns regularly too. I found the 222 shot better dirty by a long trial and error. Why it does that is beyond me and I really do not like it.
I am really thinking about rebarreling it for that reason. I have really polished it a lot, but to no avail, it still shoots better dirty and fouls up quickly. All my other guns shoot better clean, unless a rimfire and they seem to shoot better dirty than clean. Why do you or anyone else clean the bores on a regular basis? We use non corrosive primers and a little oil down the bore would keep it from rusting even if fouled up. It is to maintain accuracy is it not? So if maintaining accuracy involves a dirty barrel then so be it. I am not being a wise guy here.
I think you missed the point of polishing the bore. It is not to skip cleaning, it is to make cleaning easier and not have fouling collect in the bore deteriorating accuracy as it is shot getting worse and worse with each group fired. I do not polish bores at the range (my back yard
). I only do them after a through cleaning between shooting sessions and once they start shooting and cleaning the way I think they should, I do not polish any more. I have a 223 barrel that would start throwing fliers after just three shots. I had to polish it up a lot to smooth out the bore, really a lot. After I got down to where I wanted it, it shoots the same out of a clean lightly oiled bore as the 10th shot. No change of impact, nice tight groups. It cleans up really slick too. No copper fouling. I just run a couple of solvent patches down the bore followed by clean patches until they come out clean. Some times I have to repeat to clean up if it was a long session. I then run a patch down soaked in Kroil followed by a dry patch. I am then ready to go at it again or store it way. I used a lot of foam cleaning up copper fouling before I polished the heck out of the bore. Now I do not need to use any foam. To each their own I say, just trying to pass on what works for me.
