Before I start, please, please, please don't be nasty!!!
My Dh shoots. He has a agreement to shoot rabbits on some farmland, a local golf course and in the local Army barracks, where they are in abundance and doing lots of damage.
He is also a qualified Deer Stalker. Twice a year, he will spend a week in the forests in Scotland, culling Deer for conservation. Basically, so he explained to me, the Deer need to be culled to prevent mass population, which would cause devestating distruction to the forests and (for reasons he did go into but I can't remember) if they are not controlled they may become extinct.
When he shoots one, it's a direct shot to the heart and the animal dies instantly. He then has to perform a 'post mortom' so to speak. If he finds any defects in the Deer he has to report them to the head game keeper for the land he shoots on. This is to ensure that the herd are all kept healthy and there is no chance of genetic defects being passed on through breeding.
He won't bring rabbits home (because I don't want him to!) his shooting partner or the farmer have them, but he does bring venison home. TBH, he then gives most of it away, I tried it but it's a very rich meat, not my taste.
