I was chatting to a mate i'm mentorting the other day who said he met a bloke at a gun club who was explaining how his big-bore airgun was just the thing for Roe and that he was using his on them in the New Forest. Call me a traditionalist but I would take some convincing to take one of these to a deer / pig which, apparently, they are certified for.
I was gaping like a fish when he put a pellet in my hand that the chap had given him.
Next to a 6.5x55 131 grain softpoint... personally I think when it comes to a welfare issue like a quick kill 'less is not more'. Be interested to know if these are more widely used than I expected or if some authorities will even ticket them for such quarry.
