It was a category of ammunition, not a specific firearm.
Yes. It falls into the ORM-D category.
This category covers establishments primarily engaged in manufacturing ammunition, not elsewhere classified, or in loading and assembling ammunition of more than 30 millimeters (or more than 1.18 inches), including component parts.
Containers in this category include ammunition boxes, tool chests, wooden cigar boxes, and cases for packing produce.

No, due to the Hague Convention (which predates the Geneva Convention) signatory nations may not use ammunition which makes death inevitable or causes undue suffering. Expanding ammunition (such as hollow points) are held to fall into this category.
