if you forget the US use, then Malaysia, Northern Ireland, the Falklands,Vietnam, The first Gulf war (and probably the second) Afghanistan, Rhodesia, generally in various bush wars and insurgencies, and as many other Historical conflicts as you could manage to research!Of course I'll drop this on the table. As HEYM SR20 alluded to. The .30-06 is Meuse Argonne; Wake Island; Bastogne; Chosin. The 7.62 NATO is to that what exactly? Part of what I do enjoy is the connection, the links, that something that binds us to those we knew, or never knew, that came before. Like using my late father's shotgun that he had new in 1919 as a twelfth birthday present. Or an old hammer gun wondering who owned it and what they did with it and indeed what became of them. The .30-06 is overlong, antiquated, uses more powder, needs a longer action. But maybe it needs that extra length to also accommodate the ghosts of history that it carries within it. The .308 is a good, efficient, effective and etc., etc., cartridge of 52mm length. And it has that shorter case as it contains no soul.
