According to the abstracts in the zone I'm in rife is NOT allowed for Grey squirrel, but it doesn't specify if I can use a rifle or not for red squirrel which is open season year round. I called masswildlife and got no usable answer. (Suggestion that an air rifle would kill one, but a smallbore rifle would be good too, but no mention of legality or not, just a "Be careful, don't shoot into the air" message) I was wondering if anyone knew one way or the other.
