Thought that I would give you guys an update. Went out today, and took the 25gr Hornady HP's with me. I committed to taking at least a few foxes to see what would happen. I was not disappointed. The first fox was a one hit wonder. I was able to drop him in his tracks at about 40 yards. I found two holes, but the are very small. The damage underneath the pelt was still impressive, though not as bad as with the 20gr Accu-tip bullets, that are officially on the shelf.
The second fox was not quite what I had intended. I looked up and there it was. I got behind the scope, centered on the chest and let the round go. Don't know if it was the foxes downhill orientation to me, the fact that it was slightly above me, or if it was the range, but the shot dropped in low, and took off a hind leg, just above the knee. It turned, and before I could get another shot, Dave threw a load from his 12 gauge at it. It took a couple of pellets, squalled and spun, before a headshot from the .17 finished it.
Here are a pic of the first fox, please note the lack of damage:
Here is the second fox. You can see that the left rear leg is broken, and that the head is mangled.
I am very happy with the results. The 25gr Hornady's did exactly what you all reported that they would, and you were all right. I will continue to try to develop a load that is even more fur friendly, but I can rest easier with my new fur getter.
