I've not had but a couple of bang-flops. I and my buddy (who owns the land where I hunt in MS), almost always have the deer run 20-30 yds. However, we never have a problem with finding them, even after it gets dark, since we seem to always have a decent blood trail. We like to aim for a behind-the-shoulder, center-chest, broadside shot (when the deer cooperate). We don't take Texas heart shots. It is heavily wooded where we hunt and we have shooting lanes cut to give us about 100 yard max shots, though most of our actual shots are closer than that. The deer just suddenly materialize and you don't have alot of time to shoot. So, that's why we aim the way we do. It does not seem to matter what caliber we use, as we have used 270, 30-06, 350 Rem Mag and 444 rifles with similar results. The only bang-flops I've had is when I've accidentially hit the spine (yes, it does happen once in awhile). As an aside, my buddy just got married and his new wife likes to hunt. So, he built her an elevated wooden box stand, where she hunts over the only wide open area near their home, that overlooks a huge food plot. She has used a 243 to harvest all her deer, which almost never travel more than 10-20 yards with alot of them DRT. However, she is picky about her shots and only shoot at deer that are broadside and no more than 50 yards away. I have thought about sneaking into her stand to hunt when she's away but I'm afraid of knocking over the microwave and color TV (just kidding).
