I haven't shot anything, YET, but like the comment about the time the arrow takes to get there the farther out they are. That's what I notice about the lobs I take at longer distances mostly to watch the arrow fly. 20 yards seems maximum for me, with the closer the better.
You have to be well set up though, my chance last season at a nice 8ptr was about 10 yds, but he stopped and looked right up at me and Mexican stand off time for about 2 seconds and back behind cover he went. I'm too new to be too critical, but longer shots at small game are seen to be OK, but isn't that a bit disrespectful of the living being? Poorly hit anything is not good.
