some brilliant advice from the above all i would add is wrap up warm (or in summer be mindful that it can get very hot) and take a comfortable cushion often best shots are from a sitting position and bot these tips will allow you to stay on target for the longest time. last tip look for any patterns in the rabbit burrows are they in a line or clustered together and if there is a pattern e.g on a bank or on the side of aditch take advantage of this when choosing your shooting position.
