I recently purchased a 223 upper at a gun show. My question is can I use ammo labeled 5.56/223?
Or do I specifically have to look for ammo labeled 223? All my other guns were 5.56/223 so I never had to worry about this. If you can shoot 223 out of a 5.56 then why would anybody ever make a 223 barrel? |

I recently purchased a 223 upper at a gun show. My question is can I use ammo labeled 5.56/223? .223 barrels should not fire ammo that is labeled 5.56. There is a difference in pressures. If you can shoot 223 out of a 5.56 then why would anybody ever make a 223 barrel?
For better accuracy. Longer throats in the 5.56 chamber are great for handling higher pressures, but they can reduce the accuracy. |

What about the ammo that is labeled both 5.56 and 223? Does that mean the ammo is 5.56 or 223? I would imagine if it is marked both 5.56 & 223 than it would be 5.56, better to be safe and use it in your 5.56 ARs only. Which ammo in particular are you referring to? |
