[edit] Proper cartridge name in Wikipedia

There several pages in Wikipedia that are meant to relate to the .357 SIG cartridge, many of which are incorrectly named or do not conform to the de facto naming standards present here on Wikipedia.

The correct naming convention for all designated English-unit cartridges in Wikipedia includes the decimal before of the cartridge name, regardless of whether or not the numbers represent the actual bullet diameter of the cartridge. Also, with this particular cartridge, SIG is an acronym for Schweizerische Industrie Gesellschaft. As such, SIG should be capitalized.

All other .357 SIG pages (i.e. 357 SIG, 357 sig .357 sig, etc...) should point to this page.

I would also like to add that there are several cartridges in existence that do not conform to this non-decimal naming convention, yet are commonly known by their approximate caliber. For example, .45 ACP (uses .451" bullets), .45 Colt (uses .454" bullets) and .45-70 (.458" bullets); .380 Auto (uses .356 bullets); .44 Magnum (uses .429" bullets), etc... I do not see the necessity in making such a differentiation here on Wikipedia when it is not widely used in any case. Raygun 02:02, 31 August 2006 (UTC)

Note on cartridge name and use of 40 S&W brass Joe4570 The proper name is 357 SIG as defined by both CIP and SAAMI, the standards group's released drawings, as petitioned by the manufacturer. The SAAMI cartridge and chamber drawing is dated 7/19/64.

The documented headspace in on the case mouth, however, handloaders frequently headspace on the shoulder as is the norm for bottle neck cases. The drawing reference dimension to a mid shoulder is 0.677"-.007". The problem with conversion of 40 S&W brass is that it results in a 0.020" shorter neck after forming and the 357 SIG already has marginal bullet contact surface area.—Preceding unsigned comment added by Joe4570 (talk • contribs) 14:50, 9 April 2008 (UTC)

[edit] Headspacing

The "necked" .357 SIG round offers high reliability and potentially improves accuracy as the round headspaces on the shoulder (angled or sloped part of the case) of the cartridge in a similar way to rifle rounds.

Unlike most bottlenecked cartridges, the 357 SIG headspaces on the case mouth; cartridges that are too short can result in serious malfunctions of the guns in which they are used, possibly leading to serious injury.

Well? Which is it?

According to the 48th edition of the Lyman Reloading Handbook, it headspaces on the case mouth. —Thernlund ^{(Talk | Contribs)} 18:09, 20 March 2007 (UTC)

[edit] Article title

I understood that the correct name of the the round was "357 SIG", not ".357 SIG", because this was not a .357 caliber round, it was just named "357" because it was designed as a competitor to the .357 magnum round. If I am correct, then the article should be moved to "357 SIG". Bradford44 13:39, 27 April 2007 (UTC)
