Template talk:Infobox firearm cartridge

message: I'm going to do more work on this template here soon.  Make more fields optional, and maybe move it to a better name (and fix the pages that use it of course).  Even add an image field for displaying diagrams or photos of cartridges.  Unless someone has an objection?  Thernlund (Talk | Contribs) 12:10, 7 January 2007 (UTC)
thread_title:  More work 

message: Just spent some time doing lots of work on this template.  Unless someone has opinions, I'm going to keep going with stuff as I think of it.  Anyone?  Thernlund (Talk | Contribs) 22:29, 8 January 2007 (UTC)
thread_title:  Lots of work 

message: Added new fields for more detailed ballistic data.  Going to add a field (or fields) so a source can be included.

thread_title:  Ballistic data 

message: The sample for copy-pasting of this template displays "|case type=". For that field to display properly when Wiki users copy-paste it into an article, it needs to be "|case_type=" (underscore instead of space). In fact, I've noticed several articles where the case type doesn't display in the infobox because of this, and manually corrected them within the articles. — Red XIV (talk) 06:19, 7 August 2007 (UTC)

message: I know there are already a lot of fields, but aren't we really missing the pressure field, like max CUP or max PSI rating for the cartridge? Arthurrh 04:06, 15 August 2007 (UTC)
replies: text: I'm working on adding such a field.  As well, I'm working on adding a "case capacity" field.  I'm sure I'll have concerns though so stay tuned.  —Thernlund (Talk | Contribs) 20:21, 4 September 2007 (UTC)

thread_title:  Metric ballistic data? 

message: The ballistics data tables are difficult to process partly because there are so many abbreviations (e.g. FMJ, LFN P+, WFNGC, XPB, and the list goes on). I would like to request that a link to Bullet#Bullet_abbreviations be placed below this table in the template. This would make the information somewhat more accessible. 
Ideally, the abbreviations used would be linked (with a named anchor) to a glossary entry so that clicking on XPB would take the reader directly to the expansion of that acronym, much like Glossary of nautical terms. This would probably be harder to implement and require a new page to be created, but would be much more useful. Attys (talk) 02:41, 3 September 2012 (UTC)

message: The .300 Winchester Magnum is showing 180grains = 12 g AND 190 grains also equal to 12 g when it should be 12.3 g.  Anyone know how to fix this template to NOT use an integer function on gram numbers larger than 10? 97.85.168.22 (talk) 03:16, 27 November 2012 (UTC)

message: How do i go about getting the link used in the "Primer" parameter corrected? It currenly points to Percussion cap, which is a kind of a priming system, but not a primer in relation to modern firearm cartridges as used by this infobox. The parameter should point to either Primer (firearm), or more specifically to primer. I am Infobox-illiterate, so i'm not sure how one goes about fixing them.

thread_title:  "Primer" Parameter Link Error 

message: :Wikipedia:Manual_of_Style/Infoboxes states: the purpose of an infobox: to summarize key facts in the article in which it appears. These firearm cartridge infoboxes usually contain information which does not appear in the article. I feel therefore that there should be a way to reference the information in the infobox, particularly the cartridge dimensions and specifications. 
I have tried adding references to Pressure data (to either SAAMI or CIP publications), and I cannot get it to work; If I add the reference to the max_pressure field it breaks unit conversion function, if I add it to the pressure_method field the reference shows up as gobbledygook. Perhaps we need another field to contain the reference for pressure data? Or perhaps I should insert a paragraph into every article containing the pressure and reference.
Similarly, there is no way to add a reference to the cartridge dimensions without breaking the unit conversion. I considered adding the reference to the text field case_type, but then it appears that the reference only applies to that field. Again, perhaps an additional field could be added into which the dimension references could be entered. But then it wouldn't be clear which dimensions come from which reference. I'm particularly concerned about the "case capacity" field. Most of the dimensions for standard cartridges would come from SAAMI or CIP, but they don't publish case capacities. Where they don't appear in the text of the article, these case capacity data really need a reference.
This infobox is a great resource, but still has some room for improvement, I think. I will probably continue to crystallize my ideas for enhancing this box as I enter more data into it for various cartridges.

thread_title:  Infobox guidelines and referencing data 

message: Can we add bore diameter to the template? This would make it easier to compare metric and imperial cartridges, since metric cartridges are often based on the bore land diameter rather than bullet diameter. More specifically, I hereby suggest the template should include both:
* Bore diameter (aka. bore land diameter),
* Groove diameter (aka. bore groove diameter), and
* Grooves contour, usually the number of grooves. For example, with conventional rifling "number of grooves" can be specified, for polygonal rifling the type lik "hexagon", "pentagon", etc. may instead be specified, while for smoothbore this field is not applicable. (I don't know if polygonal rifling is ever specified in cartridge standards, or if this is in practice is just something firearm manufacturers may choose to use.)
Anyway, a recommandation on the three mentiond parameters is normally specified for each cartridge by CIP and SAAMI, see for example .260 Remington#Design and specifications.

thread_title:  Adding bore diameter 

message: At this point, the infobox contains information about (kinetic) bullet energy for listed example loads. Energy can easily be calculated based on the muzzle velocity and bullet mass by the formula 0.5*m*v*v, where m stands for mass and v stands for velocity. I hereby suggest we add bullet momentum to the infobox, which can easily be calculated from the formula m*v. The metric unit for momentum is newton-seconds (N⋅s), while the imperial measurement is slug-foot per second (slug⋅ft/s). Momentum is the most important measurement of recoil, see Power factor (shooting sports). If recoil gases could be accounted for, momentum would be the amount of recoil from a cartridge. Momentum is also the most important measurement in shooting sports to be able to knock down steel targets, and is informally known as "knock down power" in the self defense community.
The reason I stated "bullet" in front of energy and momentum above, is that powder gases also contribute to the total energy and momentum, but these are difficult to account for. To clarify this for our readers, "energy" in the template should be renamed "bullet energy", and momentum should be added to the infobox as "bullet momentum".

thread_title:  Adding momentum 

message: When recently looking at the differences between 9x19mm and .357 Magnum rounds, I noticed something odd about the information presented in the Infobox on each page.  On the 9x19mm page, the bullet diameter is listed as .355 in (9.01 mm).  When looking at the same information on the .357 Magnum page, the listing shows .357 in (9.1 mm).  In actuality, .357 inches is 9.0678 mm.  It appears that when entered as a metric value (is_SI_specs= yes) the calculation is giving the converted value (.355) with the expected precision, but converting from .357 to metric, it is rounding in a gross manner.  I would prefer to see the calculation presented with at least two digits to the right of the decimal, for more precise measurements. Mgg4 (talk) 22:10, 5 March 2021 (UTC)

message: Many pistol cartridges, when used in SMGs with longer barrels, have shown quite different ballistics with the same loadings. Why can't we provide more than one test barrel length data in the template? Ain92 (talk) 09:30, 16 February 2022 (UTC)
