Besides the SA80 and Colt M16icon chambering (testing) of the 4.85mm cartridge, were any other assault weapons tested ? It is my understanding that this was a very accurate cartridge. There were some wildcats such as the 5mm/223 plus the factory 204 Ruger cartridge which are very close in performance. Examples in photo 4,85mm, 224 Winchester and 222 Rem Special which became the 5.56mm
