Should the question be "if I only had 1 rifle to survive the zombie apocalypse with"
The answers all might come back to 308. Very difficult to get the amount of performance you can get from a small amount of various, common powders. The shear amount of surplus (free) brass, the offerings in 30 cal bullets AND 5000 round barrel life out of anything else.
I swapped barrels to 708 for obviously reasons, but kept my 308 barrel for the above mentioned event and I still pickup and horde 308 brass
