The '''.224 Boz''' cartridge was developed in the late 1990s, designed as a candidate replacement cartridge for adoption as the standardized NATO ("[[STANAG]]") [[Personal defense weapon]] PDW round, originally solicited to replace the longstanding NATO standard (STANAG) [[9×19mm Parabellum]]. It was going to be the British entry, to be evaluated alongside the Belgian FN [[5.7x28]]mm and the German [[HK 4.6×30mm]] armor-piercing cartridges. The solicitation would also seek to find, test and standardize a PDW cartridge capable of, at the minimum, defeating the Collaborative Research Into Small Arms Technology (CRISAT) body armour of the time.<ref name="auto">{{cite web |url=http://www.civil-defence.org/products/ballistics/boz224/boz224.html |archiveurl=https://web.archive.org/web/20050404115225/http://www.civil-defence.org/products/ballistics/boz224/boz224.html |archivedate=2005-04-04 |title=.224 BOZ Ammunition and Weapons Programme |website=Civil Defense Supply |accessdate=10 October 2013 |url-status=dead }}</ref><ref>{{cite web |url=https://www.youtube.com/watch?v=Py9MJUmdQ4ohttps://www.youtube.com/watch?v=Py9MJUmdQ4o |title=NATO PDW Trials: The Forbidden Saga of "MP7 vs P90" [ Collab with Oxide ] |website=[[YouTube]] }}</ref>
==Design==
The .224 Boz began as a 10mm Auto case necked down to {{cvt|.223|in|mm}}. Original trials were successful, with this round firing a {{cvt|50|gr|g}} projectile chronographed at over {{convert|2500|ft/s|abbr=on}}.<ref>''Guns & Ammo'', November 1998, p64</ref>  During development a version based upon the 9x19 Parabellum case was also evaluated, which carried the significant advantage of being able to be utilized in pre-existing NATO standard 9x19 Parabellum caliber firearms by means of a relatively cheap barrel and caliber swap.<ref name="auto"/>  The [[22 TCM]] takes advantage of this same concept in its sub-variant, the 22 TCM 9R.
