Lad if i was just out for a bit of sport well and good i would let a certain amount run ,but when ye have a farmer ringing ye asking ye to come up and try and sort a problem ,it has to be done,I could of let them run and told the farmer lies ,but if he is still losing lambs ,he will be thinking i'm not doing a very good job and the first rifle mans that asks him for permission he will grant it and wipe out the whole area
