The ammunition is sold by AIM as "surplus". If it's older surplus military ammunition, it just may be corrosive. Somebody look into that will ya?
Copper-washed steel case, berdan primed, non-corrosive (I hope) primer;
Two pulled bullets weighed 93.1 and 92.5-gr;
Bullets are copper-coated steel-cased;
Cartridge case and bullet are magnetic.
