| 25 Winchester Duplex 6.35x48mm (FA-T125) |
 |
| The 6.35x48mm Duplex Experimental Cartridge (.25 Winchester) was designed by Frankford Arsenal and manufactured by Winchester. 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. One of the listed loadings is a Double Ball, called (FA-T125). The cartridge was one verison based on the .25 Remington case, the (FA-T125) measured 6.35x48mm and loaded with two 3.4 g (53 grain) Projectiles firing at (2,600, front bullet and 2,460, Back bullet) feet per second . However, the decision against the .223 was overturned by further trials in 1959, which again found the AR-15 superior to the M14 and recommended that its development should be pursued as a replacement for the 7.62 mm rifle, which had only been formally adopted for service two years before. |
