Yes, but 5.56 ammo should not be used in a .223 Remington chamber.
Only .223 ammo. There are different bullet weights.
No. If it does not have 5.56 on the barrel then use .223 ammo.
>.223
No. Dimension-wise, they are similar, but there are differences in neck angles and case thickness. .223 Remington ammo can be fired in a 5.56 chamber, but 5.56 ammo should never be fired through a .223 Remington chamber.
its sniper ammo
yes. the 5.56 is the 223 caliber ammo.
NO the .223 is a totaly diffrent round than the .223 WSSM
.223 and 5.56 x 45 can SOMETIMES be used in the same barrel. Mostly in AR style weapons.
.223 Remington ammo can be safely cycled through a 5.56x45 chamber - 5.56x45 ammo should not be cycled through a .223 Remington chamber. Both types may be cycled through a .223 Wylde chamber, but .223 Wylde may only be cycled through a .223 Wylde chamber.
you can fire both 5.56 and .223 ammo in a rifle chambered in 5.56...but not the other way around! In a rifle marked .223, you should fire .223 ammo only
The max range for .223 is about 300 yards.
