After all these discussions about barrel break-in and new barrel technologies what cleaning regiment and products do you use? I got a few PM’s asking me mine so I thought I’d share mine and throw it out to board to see what you use. If I’ve shot a few hundred rounds without cleaning, I’ll normally shoot brake or carburetor cleaner down the barrel and give it a brushing with my Iosso nylon brushes. Any carbon build up is gone. Then I follow my normal cleaning regiment outlined below. Since most of my barrels are SS Rock or Broughton match barrels I’ve taken the easy way out. BTW I use a Lucas bore guide with Tipton carbon fiber cleaning rods and jags. For cleaning I use Wipeout and Wipeout accelerator. In my match barrels, I usually pass a few patches of soaked Wipe Accelerator through to push out most of the loose gunk, followed by Wipeout foam bore cleaner. I leave the Wipeout foam in for an hour or so. With Wipeout still in the bore I use a Iosso nylon bore brush. I usually give it 15 to 20 good passes, then patch the bore out with dry patches. I push a soaked patch of Kroil through followed by two or three dry patches and call it done. For my .300 WSM with the factory barrel, I use the same method except I let the Wipeout sit in the bore for 3 to 5 or 6 hours, brush, patch clean and oil with a few dry patches. I see more copper fouling in the .300 WSM factory barrel so I let Wipeout sit for a few hours. Since my .300 WSM is strickly a hunting rifle it never sees more than a few range rounds to verify my zero and any rounds I shoot when hunting. My bores sparkle and are very clean when looking through a bore scope (when I can get access to my buddies bore scope). No carbon build up, copper fouling, just a very clean bore. Not sure if it’s right or wrong, you agree or disagree, but it works well for me.
