Yeah 5.56 is good when you’re humping a rifle and combat load for 10-12 miles with a billion other pounds of gear. The weapon is lighter the ammo is lighter so it allows you to carry more ammunition at the same weight as your enemy which when used in conjunction with controlled rates of fire let’s you run a gunfight longer. Aside from the military roll there’s MUCH better cartridges to run stateside for different stuff; hunting, self defense, long range etc.
I still love my 5.56 but only in the AR platform. No need for a bolt gun, or any other roll really.
guess it’s a good medium sized varmint round too?
