Sweets 7.62 for heavy fouling,,
Hoppe's #9 for a cleaner and lube..
We tried the BreakFree when it first came out, Hey Teflon, GOTTA be good... when we used it down the bores of our PPC match pistols, our scores dropped !!!
We put the back into a Ransom Rest, and ammo that was previously shooting MOA and less, was now doubling the size of our groups... after we putt about 200 rounds of wadcutter through the bores, our groups came back.. So, I love BreakFree for lubing slides and actions, but dang it I will ever put it down another bore,,, just my personal experience, and it was with three different Douglas, and Shilen barreled K-Frames.. all three same results, same cure... Just my own observations.. Other than down the barrel, Breakfree is good stuff..
