Last night, finally fixed my opinion of the .17 Fireball as a foxing rifle, along with the green filter, (again), a very nice top conditioned large dog, (Looked very Alpha male)similar in stature to the one in my gallery lying on the eight foot swathe cut machine,He made the mistake of, Hold on a Mo'....... OOH! that's a nice colour! & got an extra eye for his laxity! at 163 yds lasered, pic too detailed to post. Sub calibres are really the way forward in amongst the farm environs, where other occupied buildings are present.
