5.56 and .223
So my understanding has always been that one can fire a .223 round out of a 5.56 chambered AR-15, but you can't fire a 5.56 out of a .223 (at least, not a great idea). However, a seemingly knowledgable man told me that you can't fire .223 out of a 5.56 gun either.
Any merit to this? Thanks.
