It's definitely not something I would intentionally try to pull off, but I've had hunting partners who've had it happen while shotgun hunting. Generally happens when hunting in thick cover with not much visibility.
I shot a doe at semi-close range with a slug once, didn't see the deer directly behind her until it took off after the shot. The slug exited the first deer and I never could determine if it hit the second one. Never found any blood and the deer wasn't limping or anything when it ran away, still had me worried though.
