    Head stamp LC 68 IIRC, is a 50 cal spotter-tracer, M48A1 that is fired from a M8C Spotting rifle mounted on top of a 106mm recoiless BAT cannon.

    It is smaller than the 50 BMG and matches the trajectory of the BAT to target impact. The bullet has a primer in the tip to ignite a smoke spotter on impact and a tracer cup in the rear to produce a tracer out to 1500 yds.

    Found it!

    I guess the silver tip is the primer for the smoke.

    As the man just said, Lake City ammo plant, 1968 Armor Piercing Incendiary Tracer (the GOOD stuff!)


    There were .50 cal spotter/tracer rounds made with same headstamp, but those will have the red/yellow tip markings (do not drop those- bad ju-ju- the "smoke" is a bit of white phsphorus under that seal)

    US Military headstamps do not indicate caiber/type, but plant of manufacture and year.

    Hi. I have joined the forum today, and I live in the U.K. I recently purchased a 50 cal tracer, exactly like the one on the extreme right of the photo, all our ordnance has the arrow on it if used by the Forces. The following is stamped on the bottom of mine, can anyone I.D. it for me please.There is no arrow on mine.
    127M48A1 SB 75....
    Many thanks.

    Jungleman- welcome to the forum- When you have a free moment, stop over at the intro section, and say hello.

    As we discussed earlier, the .50 cal spotter/tracer round is shorter than the .50 Browning Machine Gun round, and has unique color markings on the bullet. The M48A1 designation is that of the spotter rifle on the 106mm recoiless. It is a stockless barrel and action mounted above the main gun tube. Yours may be Spanish- SB for Santa Barbara ammo plant in 1975. and I THINK 12.7mm is the metric equivalent of the bullet diameter.

    Here is the cross section of one: Cartridge of the Month

    As already mentioned, treat these gently. The marker portion of the bullet IS shock sensitive, and is intended to go BANG on impact. The trajectory of this shortened cartridge is the same as that of a 106mm anti-tank shell- you walked the spotter rounds onto target- when they hit, you fired the 16 pound main projectile.
