>bullet - bullets
Good idea to separate bullet damage from melee types, especially true for JHP, might also call it internal damage or maybe "rupture" if you want to have some other weapons do similar damage.
For example the wasp knife that injects compressed air has similar enough effect on soft tissues.

>high mass bullets
There's a subset of modernish small caliber firearms specifically designed to penetrate body armor. Downside is they have very little stopping power.
