My National Ammo Day order arrived last night.
While it may be non-corrosive, it's still your typical light ball ammo. Copper plated steel jacket.
It occurred to me that there are legends about cold iron and steel being extra efficacious on the faerie folk.
Something to keep in mind when making a character who may be confronted with Celtic and Nordic mythology.
