bc,
The new 17HMR is a very nice round for apx 200 yrd shots at groundhog size animals but that little .17 cal 17 grain bullet has little penetration & most probably would only make a nasty superficial wound after passing thru a beavers thick wet fur.
There are lots of trappers who would love to rid anyones pond of beavers. You can ask your local wildlife officer for names of local trappers.
