I voted 31-40 because that's the limit of my practice ranges. However, I have shot one at 44.5 yards successfully. I didn't know it at the time as I didn't have a rangefinder. I probably would never have shot if I knew it. Want back with a buddy's Nikon 440 and verified the range only because he said it was over 40 and I did not think so. I was wrong.

Now, I have a rangefinder to remedy that problem!!!
