I have a Ruger American 223 rifle. A friend gave me quite a few 5.56 ammo. He claims new rifles should be able to use either one. I bought it in 2014. Is he correct? Don't want to screw up a good rifle.
I had a 223 Bushmaster AR15 duty gun. There was a summer that we ran mostly 5.56 in training due to supply issues. When the Bushmastets got hot we would start to get popped primers. Not every round. But it jammed up several guns each training day with primers getting into the action and trigger group. I have never heard of any actual damage to the guns that I can remember.
