I'm not doubting you, but I've never heard of a snake snapping and becoming stuck in the barrel. Most snakes aren't thick enough to become permanently wedged inside a barrel, except perhaps a .22/.223 diameter barrel.
In fact, I prefer using one size-up bore snakes in my firearms (9mm, use .40cal; .40cal use .45, .45 use .50 etc.) just to get a bit more friction contact in the barrel. -but I will start paying more attention to my bore snakes and examine them for wear and fraying from now on.
If a snake did actually get stuck, I don't see why it couldn't be pushed through with a barb on the end of a rod?
