Bulk 223 ammo can be a lot of fun to shoot. The .223 Remington cartridge is an excellent round for plinking, competitive shooting and varmint hunting. Here are some things to know about this round.
Difference Between .223 Ammo and 5.56 NATO Ammo
One important thing to note about the .223 Rem cartridge is the difference between it and the 5.56 NATO cartridge. The two rounds often get lumped together because NATO modified the .223 in order to make the 5.56 back in 1980. Consequently,the external dimensions of their cases look exactly the same.
One difference between .223 ammo and 5.56 ammo involves the interior of their cases. The walls for the 5.56’s case are thicker than those of the .223, which increases its maximum chamber pressure by 10-15%. This means that the loading data will need to change if someone wants to reload 5.56 cases to .223 specs.
A bigger—and more important—difference between the .223 and the 5.56 lies in the rifles that fire them. A .223 round will fit in the chamber of a rifle designed for 5.56 cartridges and vice versa. However, issues can arise when someone tries to fire 5.56 rounds in a rifle that designed for .223 ammo.
Because the leade of a .223 rifle is almost half that of a 5.56 barrel, 5.56 rounds can end up touching the rifling of a .223 barrel. This can increase the pressure inside the chamber and lead to cases stuck in the chamber and blown cases. It can also lead to misfires, which can possibly cause damage to the rifle.
The bottom line is this: If you have a rifle chambered in .223 ammo—especially a bolt action rifle—use .223 ammo. Almost all MSR’s and AR-15’s are chambered for 5.56 ammo. If you are not sure which caliber a firearm is chambered for, it will be stamped on its barrel or lower receiver.
Finding the Right .223 Ammo Weight
The weight of .223 Rem cartridges is 30-90 grains. This broad range is what makes this round so versatile. Shooters who want to focus on target practice can do well with 55-62 grain rounds. If you want something for hunting or competitive shooting, look for rounds with a higher grain.
