I just received the 2020 Master Hunting Catalog from Cabela's/Bass Pro. When looking thru the Black Powder section (of which there was very little) I noticed that they are charging a haz mat shipping fee for Pyrodex. I thought Pyrodex was not considered an explosive, like black powder, and therefore did not require a haz mat fee. Did something change, or is this just a Cabela's/Bass Pro requirement? Not that i really care, cause I only use the real thing, but I am curious as to why the change.
