I am NOT a proponent of lamping anything other than fox, rabbit, etc. Not even Wild Boar. There are enough moon nights and proper scopes that lamping is not, normally, necessary. If there is an abundance of Roe, Fallow, or Sika, and one is not able to manage it alone, don't be so stingy and call up some mates for a drive hunt, or something of the like. If that doesn't do the trick, do it more. I guess my point is, there are an infinite number of ways to help reduce a troublesome population that resorting to lamping.
