American Pioneer is corrosive
Alliant says Black MZ is "Virtually non-corrosive." I don't know what "virtually" means but combustion always produces water, which itself is corrosive, and the claim seems solid enough from a solid company for me to try it! I have some AP Shokey's Gold. If nothing else, it will be interesting to see if they've tightened up the grain size consistency vs. AP SG.
