Being an owner of two 6.5x55's (Gustav and a Steyr Pro-hunter) which I use on boar,moose and roe-deer in Estonia. There are two other calibers (25-06 and .308) in my gun safe. The 6.5 is by far my favourite, apart from it being very accuract, the two things I like very much is it's moderate recoil and the fact that rarely do I find a different bullet (of the same weight) needs adjustment to be on the bull.
