Is this lake city ammo?

Answered by Jd, member, from AZ, United States, on July 28, 2022

Yes, This is Lake City ammunition. There are two companies that supply from Lake City ammunition plant.
The most common is from Winchester. The other is Remington. Ammo that's 5.56 labeled (NOT .223 LABELED!!) from these two suppliers are LC headstamped.
Please don't use ammo labeled 5.56 in a rifle or barrel that's labeled .223. You may have a great big KABOOM that could endanger your safety, your body, and even someone else that's in close proximity.
Lake City 5.56 cases are stronger than .223 cases.

Is this .223 Ammo?

Answered by Resipsa, member, from OK, United States, on February 15, 2022

I now know the answer. My Barrell is labeled 5.56 NATO. I viewed a couple of YouTube videos on the subject and now understand the differences between 5.56 NATO and .223 AMMO. I thought they were the same thing, or completely interchangeable, or something. I just didn't know. Thanks.

Dennys, guest, from CO, United States, asked on October 02, 2022

my barrel is marked .223 wylde. I've been told 5.56 is interchangeable with it. Am I missing something?

Expert Answer

Answered by Ethan, Gear Expert, from IL, United States, on October 07, 2022

You are correct. A barrel chambered for .223 Wylde can safely use both 5.56 and .223.
