From what I can gather rabbits are easier to kill in some areas than others. Down here I will only use broadheads. I've tried all sorts of blunts, homemade heads, rubber blunts, etc. Nothing works as well as a broadhead. You can cut the point off and leave them dull, they will still do fine--rabbits aren't hard to penetrate, and it's the massive hole that does the killing...although we have had to track several down that had less than perfect shots, it's rare to loose one that was hit.
