You are right, better to get the job done right first time!
However it has happened to us all and will happen again.
How many people here can competently despatch a wounded rabbit with their bare hands? Do you use a priest?

The biggest problem I have is finding the wounded rabbit after it has bolted. I can HEAR it, as it doesn't seem to go too far but sometimes they just elude me.
(I would like to point out that this is not an overly common problem as I am a fairly competent shot however the inevitable does happen!)
