I am assuming you are referring to the 7mm Magnum--I am in the US and typically when someone refers to the 7mm that is what they are referring to. If you are worried about recoil and were talked out of a .270 because of ammo options I would suggest the .280 or a 7x57 --you can use all the same bullets as with a 7mm--much less recoil than the 7mm and it shoots wonderfully flat...I have used and owned a .280 for years.. have shot everything from Pronghorn antelope to deer to elk and coyotes.. if meat preservation is of concern you will need to choose your bullet carefully, however with all the choices available in this caliber that would not be a problem--
