I have a pair of characters in 18th century technology setting, and one has been shot in the shoulder by a musket. I intend it to be a relatively non-lethal wound, but the other character needs to remove the musket ball without any access to medical equipment or doctors. She'd boiled water to sterilize the pair of needle nosed pliers she's found, I just need to know if there's anything crucially important she would need to know about removing a bullet. The character who's been shot would likely know, and tell her if there is, but as is, I've got him saying, no, it's pretty straightforward, just get it out as gently as you can.
I mostly just want to check if I'm missing something that completely blows the believability of this scene, because it's an important scene.
Edit: it's a fantasy world, so no fuss about historical accuracy of sanitization methods; just that approxmate level of technology. The guy was shot escaping from military barracks, and the distance the shot was fired at is fairly ambiguous, and not critically important to the story. They are hiding now in someone's appartment while they're not home, and the guy's a woodworker, and has a shop in an adjoined room. Pliers was the first thing I could think of that would likely be in there that would be useful. There's silverware in the drawers too, so she could use a butter knife as a probe if there's not likely to be anything better in the shop.
