Brent - pretty good to me
Brent,
I use a heavily oiled patch instead of the boresnake but my technique is similar. Boresnakes are great for light cleaning, I'm running them 2 - 3 times also.
Tetra or Dewey rods, bore guide when possible. Wipe down rod in between passes.
I'll do 3 - 4 brush passes, patch, brush, patch, maybe 1 more bore brush & patch. I don't worry about the patch coming out totally clean, although MPro 7 did a remarkable job.
Copper solvent every once in a while.
I use a CLP gun oil, Tetra, not ATF. I'd worry about ATF mixing with any other chemicals, my experience is that the additives can precipitate. But I worry too much about that sort of thing, probably not a concern here.
Good of you to ask, Andrewsky. I see wisdom in these threads that I wish I knew 20 years ago, esp about the rods & guides.
