Bullet or fishing weight?

[kapidr]

Found with the DFX-300 with the bigfoot coil on St. Augustine beach.. Anyone know what type of bullet it is or is it a fishing weight? It appears to be hallow but the tip is closed.

My guess bullet, looks like a 50 cal FMJ.

Definitely a bullet, it has rifling on it so it has been fired.

Appears to be a bullet. Crimp groove and rifling visible, hollow base probably held phosphorus and was used as a tracer bullet.

.50 Tracer round... Body was filled with red phospher and burned after it was fired showing the rounds flight and impact point allowing aiming adjustments.. Typically a weapon was loaded with regular ball or AP and every 5th round or so was a tracer... Aircraft and ship guns often were so loaded wheras infantry and armor did not like them as they pointed they way back to firing origin allowing the targeting of the weapons system doing the firing. Tracer rounds have evolved in using a type of phospher that emits light only visible with night vision equipment... Theeby making tracers more useful and somewhat stealthy...
