April 2022 Dubious Tag[edit]

The article states "in the United States, Washington, D.C. disallows registration of .50 BMG rifles, thus rendering civilian possession unlawful" - However, the U.S. Supreme Court held in District of Columbia v. Heller, 554 U.S. 570 (2008) that firearms registration is not discretionary but rather is "shall issue" under the second amendment to the U.S. Constitution, provided the registrant meets the requirements of statutory law. Therefore, the dubious tag was inserted concerning what are likely to be outdated references under old law. (talk) 03:03, 12 April 2022 (UTC)Reply[reply]

D.C. v. Heller is a fairly narrow ruling that primarily addresses handguns and not .50 BMG rifles. The Washington, D.C., police website only discusses registration of certain handguns. Do you have a published source stating that D.C. is now allowing registration of .50 BMG rifles? Carguychris (talk) 15:21, 12 April 2022 (UTC)Reply[reply]
Furthermore—now that I've had a moment to look up the text—I believe that the assertion in the edit summary that The court ruled that D.C. must issue permits concerning any firearm which is not a destructive device under federal statute is factually incorrect. Here's what the ruling says.
Assuming he [Dick Heller] is not disqualified from exercising Second Amendment rights, the District must permit Heller to register his handgun and must issue him a license to carry it in the home.
— Justice Antonin Scalia, D.C. v. Heller, 478 F. 3d 370, pg. 3
D.C. v. Heller ordered the District to issue a license to possess a handgun to a person not disqualified from owning one under federal law. That's all! There is no allowance in the order for other types of firearms. I have found no published source indicating that the District must now allow registration of any other type of firearm on a "shall issue" basis.

Correct Caliber Designation[edit]

Computers and electronic use of data continues to increase and is being relied on more and more.  Incorrect use of data exponentially causes issues when left in an inconsistent error state.  There is a lot of confusion when people are looking at cartridge or firearm chamberings.  It is extremely important that effort is put forth to remediate these issues.  Everyone needs to represent caliber the same way, which would be the correct way.

WikipediA is misleading many regarding to this issue.

The unit or designation of measure is Caliber.  This unit is the standard for industry, standards, documentation, and other.   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.   If one were to  say/list ".45 Cal" , this would convert in inches to 0.0045".

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.   If it was desired to have the decimal in place, the units would be left as inches and not caliber.   This would also be a little misleading as most of the time the caliber does not match the exact measurement of inches.  When specifying exact measurements in drawings the units of inches (") or millimeter (mm) are used.

It is important to know that Caliber is its own "Unit" of measurement.   It is quite unique as it is based of inches and/or millimeters, however caliber is it's own unique designation.   Knowing and using the correct unit designation is important.

The most common units are Kilograms (kg) Meters (m), and Seconds (s).  Kilograms cannot be interchangeably uses with Pounds (lbs).  Meters cannot be directly interchanged with Yards, Caliber cannot be directly interchanged with inches.  When misrepresenting caliber, it is similar to using minutes for seconds without doing proper conversion of value "and" units.  They are directly related but they have a different value and units.    Values and the units used are separated by a space.   Example 7 mm is correct,  7mm is accepted in some cases depending on font and spacing, however it is not correct, (proportional spacing with fonts). Correct case of letters (upper, lower) is critically 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).

Finding reference that support something that is incorrect does not validate arguments of incorrect designation.

To summarize, the units are Caliber not inches.  The inches are not an exact or consistent measurement  depending on where they are measured, lands, grooves, bullet diameter…. , therefore caliber is the unit used, and it does not have  a leading decimal.

Wikipedia goes by what reliable sources say, and reliable sources refer to it with a leading decimal. You've brought up this issue plenty of times before, and nothing regarding the situation has changed, so I suggest you drop the stick. Loafiewa (talk) 19:34, 13 November 2022 (UTC)Reply[reply]
It is wrong, These are not dimensions. it is the caliber. Scimernet (talk) 21:17, 22 November 2022 (UTC)Reply[reply]
It is completely wrong, Read what I have posted. Refer to what Caliber is. and make it right. Look at industry standards for reliable resources. They are already listed here. Posted articles with same mistakes may be out there. This does not make them correct. Scimernet (talk) 17:00, 11 December 2022 (UTC)Reply[reply]
I'd recommend you read WP:VNT. Regardless of how you may feel about it, the purpose of Wikipedia is to summarise what reliable sources say, and only what they say, not to alternate their details and engage in original research. If you believe there is a case to be made that it should be 50 BMG and not .50, then you're going to have to find a reliable source that supports that assertion.

Reliable resource is knowledgeable people not confusing measurement in inches with designation of caliber. — Preceding unsigned comment added by Scimernet (talkcontribs) 15:46, 31 December 2022 (UTC)Reply[reply]

The most rudimentary of google searches shows that the decimal point is used completely randomly. Even so much as the same website sometimes using it and sometimes not (see hit #3 in previous link). That being said, a quick look at Category:WikiProject Firearms articles shows that our standard (whether a guideline/policy or not, any WP:Firearm members?) is to use the decimal point. That's my uninvolved opinion on the subject, unless someone has a source that can indisputably verify one being more correct than the other. - Adolphus79 (talk) 22:09, 31 December 2022 (UTC)Reply[reply]
