I bought some of this waaay back in 94. Seems like a good time to use it or sell it. It is in 36 Round "cartons" sealed and with plenty of "writing" that I cannot read. I have fired it and it distinctly goes "bang" and rings the armor plate plenty sharp, much "louder" than my IMI 115gr JHP. MY QUESTIONS ARE : What Grain of bullet and is it corrosive. Thanx for any help.
