Bob-Co, No, I'm not saying that having sharp broadheads is not important. I was just saying that the correlation between a deer running far with a double lung and having dull broadheads is not always the case. The deer that I hit that ran far was shot with a razor sharp head that did plenty of damage, but the deer still ran far. Granted, you are more likely to have a bad hit and have a deer go farther with a dull broadhead, but that doesn't necessarily mean the same deer wouldn't travel far if a good hit was made with a sharp broadhead. I am in no way trying to say that a dull broadhead should ever be used for hunting. I hope this makes sense.
