Don't know for sure, but if it's new ammo (i.e. made in the last 30 years and not mil-surp) it would shocked and amazed if it was corrosive. I'll be bringing my coffee can of .40S&W ammo (155 grain FMJs, 1070 fps). I've got almost 400 rounds of that stuff, so that should be plenty. You're also welcome to give Miss Kaysa a try.
