You till get a bang but the next round is not chambered.
In the ammo shortage alot of folks have fired softer ammo like Tula 223 and see short cycling in premium carbines balanced for full power 5.56mm ammo.
There IS a difference in charge between 223 and .556. When I fire PMC breanze 223 or PMC Xtac556 the muzzle flash and report are noticeably greater with the 5,56
