Corrosive ammo...
Hey Guys...I've been doing some reading about corrosive primers in surplus ammo and found a wealth of info...believe it or not...on the internet. Now, as they say, opinions are like....teeth....everyone has a mouth full. Consenses is: old American made ( some say pre-1950) and ComBloc surplus ammo primers contain mercuric salts.
The most important part of cleaning after corrosive ammo use is..... Hot Soapy Water & Ammonia, which neutralizes the salts and removes any copper fouling covering the salts at the same time. In gas operated firearms such as the M1 Garand or AK47, make sure you get into every spot ( read gas tube ) the blowback gas get to. Dry off the parts then follow with your favorite oil to protect the metal from rust. Black Powder shooters have been doing this for literally centuries. Hope this helps...
