Talk:.30-06 Springfield

development of the 30-06 cartridge
Reading the article it sounds like the 30-03 were an original development, while in fact both the cartridge and the gun it was used in, were based on Mauser or other German developments.

AFAIK the 30-03 cartridge was designed by lengthening the 7 x 57 or 7.92 x 57 case. The design was done after the US army encountered the 7 x 57 in the Spanish American war. The aim was to produce a cartridge more powerful than the 7 x 57 or 7.92 X 57. You can compare the measurements of any of the 57mm Mauser cartridges, that are again based on the M88 pattern German cartridge or 8 x 57 I. The measurements are nearly identical, but the length. The agreed upon payments for patent infringement never happened because the advent of the great war.

The change from the 30-03 to 30-06 again copies the development in Europe. First the French changed the 8 mm Lebel to a 198 grain spitzer boat tailed bullet and than the German changed the 7.92 x 57 to a 153 grain spitzer bullet with a muzzle velocity of 2880 ft/s. Looking at those developments, the US changed the cartridge to the 30-06 version with a 150 grain spitzer bullet with a muzzle velocity of 2700 ft/s, about copying the performance of the 7.92 x 57 S.Jochum (talk) 04:51, 23 September 2019 (UTC)

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)

.306 designation according to the manufacturers blueprint
Someone incorrectly edited a calibration designation of Dr. Ira Leviton’s. I tried to revert it back. My edit was reverted but not the incorrect one of War Raven’s. When will my edit be validated and applied? Apoc41 (talk) 16:55, 4 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.
