The Chamber and Throat: A Visible Comparability
(Whereas I am unable to present precise diagrams right here, let’s describe how they could look). Think about a cross-section of each barrels. Within the .223 barrel, the chamber begins nearer to the rifling, creating much less free area. The throat is often shorter. Now, visualize the 5.56 barrel. The leade is a bit longer, offering extra space earlier than the bullet hits the rifling. This additional area permits for the upper pressures to construct earlier than the bullet is absolutely engaged, resulting in a smoother transition and lowering potential stress on the firearm. This distinction is critical. Understanding this distinction helps clarify why you typically see higher outcomes when utilizing the right cartridge within the corresponding barrel sort.
The Compatibility Query Answered: Can You Shoot .223 Out Of A 5.56 Barrel?
Now, to the guts of the matter: Are you able to safely shoot .223 ammunition from a 5.56 barrel? The reply, most often, is mostly sure.
