The rounds? Why would it matter if they were or not? The only thing you really have to worry about is if the caliber will fit your ear canal. Very small or very large rounds won’t work.
I mean if they weren’t they’d be shoving lead in their ears. Google says jacketed bullets were invented in the late 1800s though so it was probably fine.
Lead’s not THAT toxic. It’s not like mercury, where it seeps into your skin. You can handle lead pretty safely, just don’t ingest it or lick your fingers afterwards. And even then, it takes a lot.
Were they at least jacketed?
