🔎 UNIDENTIFIED Spitzer-type bullet??

[Detector mom]

I’ve found a lot of old bullets—from mid-1800s to 1920s—near this old house, but never one like this. Quick research kept coming up with Spitzer but I don’t know—seems like the wrong material. Greenish tinge around end. Heavy. Soaking in olive oil to see if there are any markings. Don’t see anything yet.

looks more like a .50 bmg or something along those lines

Agreed, 50cal

What is that? I am gun and bullet ignorant.

Big machine gun bullet used in aircraft too. .50 BMG = Browning machine gun.

Sorry to have to rain on anybody's parade, but... a US quarter-dollar coin is .953-inch wide. Therefore, the bullet shown next to the coin is definitely a good bit less than .50-inch wide. So it's not for the .50-caliber Browning Machine Gun or any other .50-caliber firearm.

Agreed, OP needs to show us the size with some calipers or something, but it's definitely smaller than a .50. A .50 next to a quarter would appear much larger than this.

It's a 30 Caliber Armor piercing projectile, as in 30-06
