We all agree that there are better suited calibres for foxes if the circumstances warrant it, but what do you say to the farmer, who has a fox taking lambs and the only rifle he has imediatley available to him, is a 17hmr? Are you seriously expecting that farmer to do nothing about it? This actually happens to me on a regular basis were oportunist foxes appear, when least expected.
One fox I shot last year, had a rear leg almost dangling off, were a mate had almost missed it with a .243, weeks before.
My original comment to you was were you plucked the figure of yards from??
