My photos show the early Winchester 224E2 cartridge designed for the Winchester Lightweight Rifle and the 222 Remington Special which later became the 223/5,56mm.
The Winchester cartridge could be fired in the AR-15 but the 222 Remington Special could not be fired in the Winchester. There are other variations of these early test cartridges tooAttachment 95774Attachment 95775Attachment 95776Information
