    .50", projectile identification.

    Three types of .50" projectiles were kindly given to me recently, among them were two examples of the well known observing round with its yellow over red coloured tip. The other two have me stumped though.....the example with the ( I assumed ) black tip, I took to be an armour piercing type until I looked at the base and saw a copper cap, leading me to believe that this is in fact a tracer with a discoloured tip colour ( looking at it under a strong light, it could be a very deep red)...it comes in at 604 grains and is only mildly magnetic. Perhaps some member can confirm my thoughts.

    The last type is chrome plated and my thinking is that it has been removed from a display round or some such like....mildly magnetic it comes in at 696 grains. The core showing at the rear can be scratched and shows it is not hardened.

    Tracer rounds usually have a straight skirt of full diameter all the way to the base, instead of a boat tail, and are longer to contain the tracer. It provides room for the tracer material. Yours has no room for tracer material.

    The red/ yellow tip are spotter tracer. They are used with the Recoiless round cannons ( 106mm I believe) and belong in a special shortened .50 BMG case. Talon ( before going out of business ) pulled them from old USGI spotter tracer round lots and mounted them in a standard .50 BMG case. I have a few boxes of these, and used to shoot them from my .50 cal. Very impressive, when impacting metal, they explode with a huge flash of light and smoke. More info when I can find TM info.

    those spotter/tracer rounds are quite sensitive and are not "drop safe",you should be careful with them

    I believe your .50 black tip is AP. The base looks very similar to .30 AP. I cut a few open to expose the penetrator. Likely they use the same manufacture process?

    Thanks for all the replies to this thread...still not entirely sure what the projectile in question actually is though, so I have asked my source if he has another example of the same, and if he has I shall section it so we shall know once and for all!
    Stay tuned.....

    Bockscar.
