Say, something I've been thinking about something and I'm thinking you're the only person I can ask. I know that generally temporary stretch cavity is unimportant. But I feel like sometimes it would have a different effect. For example, those "hollow" organs like the lungs and stomach. Do you think that a high velocity round striking the stomach directly could like. . . pop it? I wouldn't naturally think so but the thought of the stomach or lung stretching out like that then going back to normal provides a crazy mental image.
