I agree, since reloading for all small calibers run the same. I do not own a centerfire 17, I had run offs with a HMR. Body shots on ground pigs, etc. My friend owns one and he says the 17 is hard to get real clean because the bore is so small. I also agree, most shots are not far at night so you will get little wind drift. Depending on where you live, for fox I would use a shotgun, In the west there are very few fox, most being poached before fur season, by rabbit hunters, who also groundhog hunt. They see a fox, it is history. Coyotes are tough, but if you hit them up front in the vitals a 17 will kill one. The vital area in a coyote is about 8 inches max.
