I know I'm gonna get some flak for not having looked to hard at past threads but I just need a straight up answer.

Is any kind of Russian Bear ammo corrosive?

I ask because a while ago I took out my 91/30 and had a blast (pun intended) on the range with it. I took it home and cleaned it like I would as if I had not used corrosive ammo. At the time I was about 99% sure that the Bear ammo I fed to it was not corrosive (the stuff in the teal colored boxes) but the more I think about it the more worried I become. This worry was partically fueled by seing some corrosive ammo at a recent show that looked EXACTLY like the Bear ammo I used. I am currently about 250 miles away from my Mosin and have no way to clean it so...

Should I be worried?

On a side note I put this thread here in General Discussion because I was not sure where to put an ammo related question, which struck me as almost absurd but it happened.
