I used to hunt foxes a night in Ireland in the early eighties at night time for a living, at that time I got 25 pounds per pelt back then. I would start a 10 pm and wouldn't finish until light the next morning. Would only start hunting from November until the end of January, that would give them time to breed. Would use a .22 Hornet Rifle, with a Schmid & Bender scope never needed anything heavier than that. Some people think the need a larger caliber that's not so, if you hunt for the pelt, one doesn't want to rip it apart. Would shoot a average of 50 to 60 each week. Back then there wasn't of professionals shooting.
