My average range of shot is between 40 and 150 metres at roe and fallow, and I would not go longer for all sorts of reasons, humanity being just one of them. BUT all of my rifles shoot 1/2" MOA or better even with me behind the butt, and the reason for that is absolute confidence in a clean, humane shot when the opportunity arises, it has nothing at all to do with shooting live game at extended ranges.
Having said that, there is a certain satisfaction in assuring myself, rifle and ammunition out to 300, 400 , 500 mtres, if only to test the confidence thing on paper.
Just my opinion, and I am sure Others may choose to differ.
