Talk:.22 Long Rifle

message: 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).

thread_title:  Correct Caliber Designation 

message: In the lede, it says: " It is used in a wide range of rifles, pistols, revolvers, shotguns, and submachine guns."
"Shotguns" surprised me, so I checked the body for a source. There's a section on Shot cartridges. It mentions .22 LR shot (context suggests it's for firing from a .22 rifle), and there's mention of .22-bore shotguns using special cartridges, but it doesn't say those cartridges are .22 LR. Oh -and  it's all uncited.
I propose to remove "shotguns" from the lede, and the bit about shotguns from the "Shot cartridges" section.
And it would be cool if someone could explain how the barrel of a .22 rifle responds to having shot blasted down it. Or at least, cite the claim.  MrDemeanour (talk) 19:40, 20 September 2023 (UTC)
replies: text: , Removed "shotguns" from the lede, and removed reference to shotguns firing "special" 22 caliber shot cartridges from the "Shot cartridges" section. Tagged that section for absence of citations; I intend to remove the whole section if it remains completely uncited. MrDemeanour (talk) 15:22, 23 September 2023 (UTC)
