Luger Lubrication

[Luke]

I have used Break Free CLP for rust prevention since I first started with Lugers, and I have never experienced any surface rust . . . even though I don't clean and reoil very frequently.

That's where the good news ends for me. Last week I bought another Winchester 63 rifle, took it out and ran 100 rounds through it. Worked perfectly. Then . . . I brought it home, cleaned it thoroughly with BreakFree Powder Blast, reoiled with CLP both outside and inside. The moving parts have a good coat of CLP and nothing else. Today I took it out and ran another 100 rounds of the same ammo through it and experienced at least 6 or 8 jams, because the gun just didn't cycle properly.

Yeah, I know, maybe some guns just like to be dirty.

Of course, it could be that I had a bad box of ammo today (CCI LR Solid Point MiniMags), but
I am wondering if CLP is simply a bad choice for the moving parts.
Has anyone else had this kind of experience?
