| ~ The Winchester .224 Experimental cartridge was Winchester's design for the 1957 trials before the adoption of the US M 16 Rifle. The E2 case was 45 mm long vs the E1 case at 43mm long, to increase case capacity to decrease pressures. It was one of the experiments in the Mid 1950s and early 1960s by the USA and NATO to develop a new Service Rifle Cartridge. All experiments were scrubbed after it was decided to adopted the 7.62x51mm, (308 Winchester) as the new NATO cartridge As with all experimental cartridges, LIMITED SUPPLY. |
