Point taken, but we don't use .223 in the military. We use 5.56mm
Remington had three great varmint cartridges. .222 Remington, .222 Remington Special, .222 Remington Magnum.
The military found the .222 Remington Special to be almost perfect for their use.
Meanwhile, if velocity frightens the news media, they should look at the 22-250. Velocity is 4000 fps, compared to the 5.56 MM which is 3000 fps.
I guess the 20-06 is “safer” as it is only 2,700 fps.
