Just FWIW, thought I'd add my two bits. For decades I had used BreakFree as a general cleaner, lubricant, protectant. Never had a problem with it on 1911s, M29s, Combat Mags, etc. But, I am now wondering if it may cause problems in certain applications. Going through a J frame rimfire phase, used BF on them, blue and stainless, in the same manner as I did with my center fire Smiths (J, K, L, N, S). Began having difficulty ejecting empties with all of them, whether .22 LR or .22 Magnum (3 ea M34, 1 ea M651, 2 ea M51). It was often necessary to knock empties out one at a time with a cleaning rod (I prefer to not pound on the ejector rod unless its an emergent situation). The guns spanned manufacturing dates from the mid 1960s through the early 90s. This was consistent behavior with all 6 rimfires, with all the different brands of ammo I could find to try. Prior owners of the guns reported no such problems, tho they did say they used the old Hoppes #9 liquid for general cleaning. They reported being able to go through 50 round box after box without any such problems. Tip it up, hit the ejector rod, reload. The BreakFree spanned dates from mid 1970s to early 2000s.
