Contrary to every cop show and kick-ass heroine you've ever seen onscreen, low cut tops and firearms are not a good idea, at least not when you're really shooting.
Titburns and toeburns are no fun.
Now, if you shoot a lot, one that you may find hard believe can eventually happen.
Historically (up until two years or so ago, when the prices went zany) I shot around 250 rounds per week.
That's a lot of chances for weird shit to go down.
I once had a .22 casing get part way up my nose. It fell out immediately.
The worst was a steel .45 super (Just like a .45 auto only much hotter loads) casing land and stick between my ear and head, like how blue collar smokers do with cigs. That's hard to pull off if you're wearing shooter's glasses, as there's already something in there.
By the time I felt the pain, it was sorta stuck there. Took a layer of skin but no permanent damage.
