I’m probably not the best person to speak to on that front, I have 7 rifles conditioned for deer plus a .243 conditioned for fox and AOLQThis is really helpful, thank you. I had assumed that boar would be .270 minimum and that 6.5cm would be borderline on red stags, but I suppose as VSS said it’s where you put it. I do like the idea of a lightweight 270 for hills and a mid weight 6.5cm for the rest/range… I imagine many rifles could be a slippery slope however!
That said only 3 get used regularly for deer, 25-45 for roe and muntjac, .280 for fallow and bigger and 6.5x55 that covers everything. If specifically going for larger deer the .280 is always the first out of the cabinet. If I had to go to one rifle the .280 would probably be it but it is a big lump of a rifle, 26” heavy barrel with an SL5 in a macmillan A4.
The 25-45 is much lighter with a 25” sporter profile and no mod, a much nicer rifle to carry about.
(The other 4 are deer legal range rifles that are primarily for target but also conditioned for deer)
