That one is .177. Head shots only or they run off and are hard to recover. It works exceptionally well!
I grow pecans for a living and that is not a pecan but defiantly in the hickory family.
In my orchard we don't want to miss so we use a 12 gauge no choke, and 6 shot.
That way you can get the little thief on the run. We killed over 600 last fall, and will be dusting off the guns agin in two weeks.
