I'm looking into the baser r8. I was going to go .308 but have the opportunity to try something new if I wanted I guess? Was looking at the calibre list and basically I'm after a one for all cartridge, from roe to fallow, to driven boar. I have a separate rifle for foxes now, so this is purely deer and above. 7 x 64 caught my eye as something different, but would ammo supply be a problem?. Thankyou.
