.223 loads in a .556

[Germz]

5.56 brass will handle .223 loads, what you DO NOT WANT TO DO is shoot 5.56 ammo in a .223 barrel, when you buy a barrel make sure its a 5.56 barrel.

to be more specific, you don't want to shoot 5.56 in a .223 REMINGTON chamber.

5.56 is perfectly fine in .223 WYLDE.
