Let's see... Remington makes a variant of the 700 chambered in .223, I believe the Ruger M77 is available in .223... not 100 percent certain about the Winchester Model 70, but I believe it is or was available in .223. .223 Remington ammunition can also be cycled through rifles chambered for 5.56x45, such as the AR-15, Ruger Mini 14 Ranch (the Target models have a dedicated .223 chamber), variants of the Daewoo K2, Kel Tec SU17, some AK-based rifles, etc.
Yes, guns shoot bullets
No.
5.56 and 223 cal. are the same cartridge...........
Yes it does, unless your barrel is stamped .223 .
The guns used in war to shoot down planes are called antiaircraft guns.
Yes, they do shoot the same projectile although the 22-250 takes a heavier charge of the same powder over the .223.
Ar-15 for one. You can use .223 ammo in 5.56 barrells as well.
guns that shoot.
yes. the 5.56 is the 223 caliber ammo.
"Ah, shoot, I left my homework at home!"Guns shoot bullets. People shoot guns.
a license
While outwardly they appear the same and they both use the same bullet, the 5.56 has thicker case walls and a smaller capacity for powder. The 5.56 is the standard NATO round and guns chambered in 5.56 will shoot .223 with no problem at all. The opposite is not always true because the 5.56 will produce higher chamber pressure and it's not always safe in all guns chambered in .223. Also, you cannot use .223 reloading dies for 5.56 brass. The brass will not cycle through the die at all.
