.308 caliber is by far the most popular. Nothing else even close. There are billions of firearms manufactured in this caliber all over the world such as Russian, Chinese, Brazilian, etc. manufacturers; AK-47s, M-1s, 303 British, etc. There are military and civilian warehouses stuffed with .308 caliber ammo.
You don't believe data? The .223 ammo sales is 3.87 times what the .308 sales are.
