mobjacker,
Mike is correct, all those rounds are corrosive. No big deal. Use boiling water to dilute the salts after shooting, oil the rifle and put it away. 30-30 remchester does make a good point in saying that some of these rounds may cause more trouble than they're worth to you as shooting cartridges. Many ranges ban AP ammo because it damages the target stands, etc. The same goes for incendiary rounds and the possibility of causing a fire.
