I disagree. Most all ammo back in WWII that the Germans and Russians used had corrosive primers, that when they ignite the charge leave corrosive salts around the area.
The barrels didnt just vaporize. The chambers didnt just start to rust/corrode/pit/disintegrate after firing the first shot.
Most likely, the weapon that you now possess has had hundreds, if not thousands of corrosive rounds put through it. Oh, the horror!
Actually the place that is most likely to see the hurt from corrosive primers is the bolt face/breech area. Especially since it can get in the firing pin channel inside the bolt.
All you have to do is wipe down that area with ammonia (Windex works wonders) sometime after you shoot it, then clean as normal. I normally pull the bolt out, clean the bolt face and the front of the bolt, then wipe out the receiver/mag follower and chamber area as best I can. Run one patch of Windex down the bbl, then clean normally (Hoppes 9, ed's red, etc whatever your choice may be). Dry patch the bbl, then oil it all down.
Every few hundred rounds (that is a lot out of a bolt gun, especially one that kicks like a mule), pull the bolt apart and clean it really well. Or do it more often (every time?), if you do desire. It's not like getting a Mauser or Mosin bolt apart is that difficult, anyways.
If you are worried about it, spend the extra 20 minutes to disassemble the bolt and Windex it all out.
Corrosion takes a long time to happen, when left untreated. Neautralize the corrosive agent, neutralize the corrosion. Yeah it may happen over **another** 100 years, but then it'll be my grandson's problem!
All my friends have milsurps and all have shot/do shoot corrosive stuff. Never a problem.
Milsurps RAWK :shock:
In conclusion, MY two cents is that you should shoot the hell out of it, and enjoy it. My 8mm Mauser ammo pile was touted as being non-corrosive, but I still wipe it down like it was corrosive. Just takes a few extra minutes.
Mausers and Mosins were designed and made for hard use, with corrosive ammo in mind. Much harder use than it will ever see in the hands of a civilian American (you know, unless SHTF

) They are super easy to clean, so just clean it and you will be fine.
