    An interesting article describing where some powders turn the PC they are in contact with to gummy mush.

    I will watch this a little further before making any decision to go to PC over my old time grease lubing.

    As propellants are either/and nitroglycerin or nitrocellulose – both which destabilize(outgas) an acidic compound, our ethylene/glycol based PC deteriorates. The slow (double based) powders typically have more stabilizers added ( reduced outgassing) therefore the effect is less pronounced. Solution? Switch to Hitek, use a paper GC, wipe the base with liquid wax, etc. I don’t use any of theses powder so not my problem. As the outgassing is NORMAL, performance of powder will NOT change. Old powder is old powder.
