[edit] External Link

I've added an external link on the 5.7x28mm page (also the Five-SeveN and FN P90 pages) to point to my blog, where I have been collecting information about the 5.7x28mm weapons system. My hope is to distill/sanitize much of the information that I've been blogging into the Wikipedia entries.

[edit] Ammunition descriptions

I've personally handled/fired both the SS192 and the T194.

The SS192 does not have any identifying markings. The T194 is green-tipped (rather than brown.)

Esteves 21:52, 6 Dec 2004 (UTC)

The references I've seen contradict each other, or themselves:

• FNH USA official product page - SS192 supposedly green-tipped, in the pic it's brown (no reference to T194)
• FN Manufacturing - T194 is green, no referece to SS192
• SPA Tactical - SS192 is green, no reference to T194

Since you actually handled the ammunition, I'll take your word for it, but we'll still have to find some concrete proof. Tronno 22:45, Dec 6, 2004 (UTC)

From the Internet Archives:

• FN Official product page T194 mentioned as green-tipped, no reference to SS192 (circa 2002) The link is borked, but cutting-n-pasting the URL should work.

The SS190 tip color also varies. Earlier versions had no color marking on the tip, whereas newer ones have a black tip. I think they changed this when the SS192 came out to replace the T194 (Since the T194 had green tips, and SS192 did not have a tip color). I have only handled the black-tipped versions of the SS190, but I know non-tip-colored versions exist.

---Added the not-yet-available SS197SR round. I will need someone else to add it to the table of ammo types as I am unexperienced in this. Velocity is 2000 fps (out of the Five-seveN), bullet weight is 40 grains, tip is blue polymer.

[edit] Photographs

I added photographs of all the civilian legal 5.7x28 cartridges and included a size comparison with XM193. I thought about using the quarter again for the 5.7x28 comparison but I felt the Air Force lighter gave it a nice Stargate-ish touch.

The "Air Force" lighter may look "cool" but is useless as a scale comparison. Please use either a ruler/measuring tape or else another very well known catridge - such as a 5.56x45. I believe the main/infobox photo should be the one that includes a size comparison. Please don't use a coin such as a US 25c piece, there are many people (myself included) who have never seen one and have no idea what size it is. Roger 16:48, 29 October 2007 (UTC)

No response to my comment above after several months, so now I'm asking - what is the lighter's size? It is an utterly useless photo! Please can someone provide a photo with real "scale". Roger (talk) 11:12, 19 March 2008 (UTC)

It was never intended to be used as an exact scale. You're obviously not a Stargate SG-1 fan, so the reference is lost. (Metroplex (talk) 19:30, 31 March 2008 (UTC))

How is Stargate SG-1 relevant? I do not understand your expectation that anyone interested in this cartrige also be a fan of a US television series. This is an encyclopedia article about a technical subject, not a personal style statement. In my opinion the photo with the very well known 5.56x45 cartridge is a better choice for the infobox, as it does give a scale indication. Please note also that there is a Wikipedia policy against using coins as scale indicators - Template:NoCoins Roger (talk) 08:16, 1 April 2008 (UTC)

[edit] ???=

I've pulled about 200 rounds apart as I use the case's for a .17x28, and reused the 40gr V max in my .223. I've found the factory bullets are sealed in place and in order to get them out at all. Must be pushed back into the case a bit to break the seal. For powder. Have been unsuccessful in finding out what the powder is. But, there's 5.0gr of a very fine/almost dust like ball powder in this blue tipped v max.

I would like to know if this is patent protected round in the 5.7 form and whether a person could chamber their own arm with this cartridge. Although, it is very low velocity and of limited use. The .17x28 case produces in excess of 3000fps with 20gr v max. Very good prairie dog round for under 200yds. —Preceding unsigned comment added by Georgeld (talk • contribs)
