I prefer blunts and head shots on rabbit and squirrel for several reasons.

Every rabbit I've ever lost has been due to a broadhead arrow whipping thru it's body on a shallow angle and letting it run off. I have yet to lose a rabbit to a blunt in the head because it drops cold them in their tracks. They're dead before they know they're hit.

If you miss on a head shot, you've got a 75% chance at a clean miss and a pretty good chance at a killing shot on the other 25%, if the arrow strays down into the neck or shoulder. Even if the neck/shoulder shot doesn't kill outright, they are stunned long enough for you to finish them with a knife.

A miss in the body, with a blunt or broadhead, stands a real good chance of ruining meat.

Even if you don't miss, it's still a mess to clean. Head shots leave the internal organs intact, so it's a quick and easy dressing job.

Side bonus is I get an intact pelt to use for fly tying materials. Or moccassin liners.

Never is a strong word and I hesitate to use it, but I don't intend to ever shoot another broadhead at anything smaller than a jackrabbit and I'll keep concentrating on head shots with my blunts and judos. If you go head shots only, with a bow drawing 50 pounds or more, use hefty arrows and keep the distance within 15 yards, blunts work like a charm.

Don't have any grouse around this neck of the woods... I use Snaros on flu flus for quail and dove.
