At the risk of starting a calibre war for the thousandth time I would like some advice on the aforementioned calibre. Before anyone comments that I am wasting my time and should buy a 270 or a Howitzer to knock over deer, save yourself the bother, I'm asking for advice on the specific calibre not what each person considers best. Until now I am a 243 convert and have knocked down every species in the UK apart from Sika but just fancy a change.
Can any 6.5 x 55 users quantify why it is such a useful calibre for deer (I don't shoot Moose) and what I should be aware of in terms of limitations if any. I have read all the usual comments like low energy/velocity but as I am only shooting UK deer, predominantly Roe and Fallow I am leaning towards this underated calibre. Please could I have some constructive comments.
