    I believe the purpose of the deep indentation in the brass was to prevent the bullet from being pushed deeper into the case. This was specifically designed for ammo meant to function through semi-auto and full auto firearms.

    Hi,

    +1 for Rufe.

    The heavy roll mark is a groove and is called a cannelure.

    There should be two digits on the headstamp which indicate the year if it is a military loading. This will tell you when the cartridge was manufactured. I believe Winchester used a "W" and two digits for the year (example W 18 for Winchester 1918) for military ammunition during WWI, but a commercial cartridge would have the headstamp WRA or WRACo and no digits for the date. Some even included the month. However, Winchester had several contracts for the government at different times and used different headstamps on each.

    45 ACP signal cartridges were also made with cannelures.

    Regards,

    Heavyiron
