Super interesting that you posted this. I hit the doe I killed Sunday evening in an almost identical spot. She was quartered to me and spun just a hair when I let the arrow go. Caused me to hit her a little back just as you did. Entry and exit holes looked almost identical. I got one lung, liver, and guts. The deer had absolutely no idea when happened when I shot her. She just hopped off like she wasn't even hit. I was in a pinch for time so I only waited around 10 minutes before getting down and recovering my arrow then looking for her. The blood was somewhat spotty but there was enough I had zero issue finding her. That exact scenario is why I continue to shoot a 2 inch mechanical broadhead. The shot was lethal with any broadhead no doubt, but I'm convinced the larger cutting diameter helped kill her a little quicker and made my job of finding her much easier.
I'm not shooting a crossbow, but if I was I'd shoot a mechanical with a 2+ inch cutting diameter specifically designed for a crossbow. Be hard for me to believe that setup didn't produce great blood trails with adequate shot placement.
