Hi,I use the hornady 17 grain stuff. I find on a still day (when I'm on form) I can clover leaf off the bipod past 150 yards, and the hilly back stop after a practise session looks like its been strafed with machine gun fire.
If you can hit the kill zone, the round will kill very effectively way beyond the skill of a shooter will allow. Agree that foxes are a controversial subject with the .17, but a head shot anchors them very nicely at 100 yards; lights out.
Thats some nice shooting Duncan
