Correct Caliber Designation

The unit or designation of measure is Caliber. Caliber is a unit "based" on inches and/or millimeter (mm). When using the designation of caliber it is not represented directly as a measurement of inches. Refer to the definition of caliber. Caliber is expressed in hundredths or thousands of an inch depending on the number of digits. When referring to cartridges, bullets or chambers the units or designation used is caliber. This would be expressed without any leading decimal. Example: 22 LR is the 22 caliber Long Rifle cartridge. It may be approximately 0.22 inches in diameter; however, the Caliber is 22.

Leaving the decimal out of imperial specifications is intentional. It is not common language to say "Point 22 LR" or "Dot 22 LR", the common phrase is "Twenty Two LR". It is also easy to miss read or not see markings with a leading dot, thus another reason the unit of caliber is used.

This page is for specifications in caliber, This is what is used in the industry. Expressing it incorrectly as for example .45 caliber would translate a measurement in inches of 0.45/100 equaling 0.0045 inches. Another example .223 Rem. If this is a caliber unit it would translate to 0.223 thousandths (0.223/1000), which would equate to 0.000223 inches. for empirical units caliber designation never has a decimal place. Metric calibers are also often but not exclusively written and used without a decimal (i.e. Caliber 762).

The title of these pages should be updated as well as the content to avoid confusion for people learning or understanding the correct terms.

Further information on the correct way to specify values and units. Values and the units used are separated by a space. Example 7 mm is correct, 7mm is not correct. Correct case of letters (upper, lower) is also important, mm = millimeters, MM who knows that that would be. Another example (5.56 x 45 mm). Both 5.46 and 45 are in mm (millimeters), note the spacing around the x and between the number (value) and the units (mm).

.30-06 is .306-.309 Apoc41 (talk) 06:57, 4 October 2022 (UTC)

The .306 caliber designation was correct Apoc41 (talk) 06:58, 4 October 2022 (UTC)

Then it should be simple to provide a reliable source for this. Canterbury Tail talk 17:32, 5 October 2022 (UTC)

.30 Govn't

I have seen plenty of references to the ".30 Govn't" round, referring to whatever cartridge was in standard use at that time, especially in the 1920s and 30s before we had two different .30 rounds. And then the .30 Carbine is called just that. No doubt there is a convention where they specified ".30 Govn't ('06)" vs ".30 Govn't ('03)", since they never overlapped in general service I have never seen either in common use. The .30 Govn't designation itself isn't very common outside period, but I have never seen it used with the clarifying addition. Although I believe ."30-06" essentially is a shorthand abbreviation for that designation. For most users it was just ".30 cal", only sportsmen would even need to clarify the "Government" part.

Sample velocities table in header

I don't think the 30 06 can do 2700 m/s. Looks like the numbers are ft/s and mixed up the units. ~2025-42056-28 (talk) 21:01, 20 December 2025 (UTC)

Looking at the sources that the data links back to, yeah. Someone got Feet Per Second and Meters Per Second mixed up and then applied the conversion to the inflated Meters Per Second giving some truly interesting velocities. I'm still new and can't for the life of me find when the change happened, but it definitely needs to be corrected. I'm out of energy to go through and double check the velocities to manually fix it to the standards it deserves, but it needs some serious work or a change to be reverted.

There is a huge disconnect between the velocity table in the infobox and the one in the "Performance" section. I suggest we simply delete the one in the infobox. The one in the "Performance" section has multiple sources.

The alternative is that someone fixes the infobox by using that good section, including its sources. Does anyone want to do that, or can we agree on just deleting the figures from the infobox? -- Valjean (talk) (PING me) 03:50, 21 December 2025 (UTC)

You can easily compare the tables on this subpage: User:Valjean/.30-06 Springfield velocity -- Valjean (talk) (PING me) 04:03, 21 December 2025 (UTC)

Dimension specifications

The numbers for the dimensions are wrong. The numbers that they say are in millimeters are actually in inches, therefore, the inch values that are given are completely wrong since they are based off the wrong millimeters. ~2025-42107-89 (talk) 01:45, 21 December 2025 (UTC)

Do you have a reliable source with the right numbers? -- Valjean (talk) (PING me) 03:51, 21 December 2025 (UTC)

... look at them. The rim diameter of a cartridge is not half a mm. Compare, for example to the 7.62x51 nato cartridge, which was derived from this one.

There has clearly been some kind of transcription error here. ~2025-42116-12 (talk) 00:06, 22 December 2025 (UTC)

I am not questioning what you say. I'm asking for a good source we can use to rebuild an accurate table. -- Valjean (talk) (PING me) 01:15, 22 December 2025 (UTC)

I think it's fixed now. Take a look. -- Valjean (talk) (PING me) 01:50, 22 December 2025 (UTC)
