to a trained ear the 1st shots .223; the return volleys were .30
Yeah . . . not quite true . . . regarding .223 and 5.56.
A 5.56 rifle can chamber and fire .223 ammo. However, a weapon chambered exclusively for .223 CANNOT fire 5.56, without conversion.
The reason: 5.56 is a higher velocity round than .223 AND the casing has a longer throat than a .223.
I own a bolt action 5.56 and also fire .223 through the same weapon.
I heard the reports of the first shots fired. That's why I stated .223 or 5.56.
Depending on the weapon used, my second guess would have been a .300 Blackout round (soft report) and widely available to be fired in weapons chambered for 5.56.
