Korean M2 Ball, Non-Corrosive?

[NEtracker]

Is Korean M2 Ball, Non-Corrosive (supposed to be 1970's manufacture)?
I was just wondering, since I've been using Windex after shooting my M1903 like I do with my Mauser & Turk 1943 ammo.
I don't want to bother, if it's not needed with the Korean stuff.

My rule of thumb...

If I'm shooting foreign military surplus ammo that does NOT have the NATO cross in circle on it, I treat it as if it is corrosive and clean accordingly.

It's hardly a difficulty to do so, and can save you a WORLD of head and heartache.
