I've just been reading all the comments about whether smaller centrefire calibres should be made legal in the UK.
There's an interesting one on there from Willie (a Scot) who has shot deer with smaller calibres to great effect and what he's saying is true. However, I like to have a little margin for error when I'm shooting. By that, I mean, if the shot is a little high, low etc...then the impact is still fatal. Last year I changed from partition heads to ballistic tips (6.5x55) and I would never go back. The internal damage as the fragments pass thorough means that of the last 12 animals I've shot (Roe and fallow) none have gone more than 10 yrds from the spot they were shot and not one bullete has travelled all the way through. This isn't because I'm a fantastic marksman, I'm average and probably a little conservative.
I mention this because all the debate is about calibre, none really seems to be about the bullet choice which is critical as far as I can tell.
