Nitpick

Once again engaging in nitpicking, the title of this article should be should read cartridge rather than caliber and even that would not be technically correct. Ideally, it should be titled "5.56mm NATO", which designates the specific cartridge. Caliber is a measurement of bore diameter, not a specific round designation. 5.56 mm or .224 inches includes a vast number of cartridges, a very abbreviated list of which would include the .218 Bee; .219 Zipper; .222 Remington; .22-250; and .220 Swift. hipshot49

Response to "Relationship to .223 Rem

Well, theoretically rounds meeting either spec (NATO 5.56x45 or SAAMI .223) will chamber and fire, the problem is that tolerances and some dimensions are different, meaning that firing a hot NATO round in a standard SAAMI chamber could result in blowing chunks of receiver at the user's face. Bad Thing™.

Not the only difference. The specifications for military 5.56x45mm ammunition also call for primers with thick, heavy cup material, to make the cartridges less susceptible to slam-firing and firing out-of-battery when used in weapons with floating firing pins, such as the AR15/M16 rifle, and also when used in automatic weapons. Commercial .223 Remington ammunition has no such specification.

Do you guys think we should actually bother with a separate .223 page?

Why is M193 listed under ballistic performance?

The US “Cartridge, 5.56mm, ball, M193” was just the US military’s name for .223 Remington, as stated in the article. As such, this cartridge is distinct from the “5.56x45mm NATO” cartridge as it predate’s NATO’s adoption of the SS109 cartridge and is built within the .223 spec (chamber pressure of 52,000PSI, below the spec of 55,000).

As such, I think M193 should be listed in the ballistic performance section in the .223 Remington article rather than this one. 2600:4040:5F52:1600:CD1E:1676:E0C1:43B7 (talk) 01:39, 30 November 2022 (UTC)[reply]

Developed by FN?

Im not an editor so ill place this request here. The line "developed in the late 1970s in Belgium by FN Herstal" needs to be moved from the summary or further clarified, as even the source cited does not mention this. It should read something along the lines of "the nomenclature used by NATO for their standard of the 223 remington cartridge." 72.23.215.113 (talk) 00:35, 16 September 2023 (UTC)[reply]

5.56×45mm NATO → 5.56 × 45 mm NATO – See MOS:UNITSYMBOLS and decision. Ahri Boy (talk) 00:19, 29 October 2024 (UTC)[reply]

Support – That linked discussion didn't have a clear decision, but this is what I had proposed there, and nobody objected. Dicklyon (talk) 04:04, 31 October 2024 (UTC)[reply]
I may start unilaterally moving every page slowly if the request is approved. Ahri Boy (talk) 07:24, 31 October 2024 (UTC)[reply]

Oppose. I don't have really strong feelings about this, but I notice that when I write it down, the habit is 5.56x45 mm. I think 5.56x45 has become a single word, a name, and not two numbers. I usually omit the mm, because the name when I refer to it in writing is 5.56x45. In speech it's just five-five-six. Jacqke (talk) 10:19, 31 October 2024 (UTC)[reply]
