Bullet?

[thedukeofdelaware]

This little diddy measures about 2.25 inches and looks like a bullet. I just need to find out how old these things are so I'll know whether or not to return to the scene of the crime and waste more time! Thanks for the ID help.

You told us your bullet's length measurement but not its diameter -- which we need to know in order to estimate the bullet's caliber. Based on comparing its diameter with the US penny in the photo, it appears to be a "boat-tailed" copper-jacketed .50-caliber machine gun bullet, dating from the mid-20th-Century to the present. It also looks fired. If you clean the encrustation off the fattest part of your bullet's sides, you'll find rifling-grooves caused by firing it through a Rifled gunbarrel. Examine the photo below, in which you can clearly see the back end of the bullet is shaped like a boat's end, hence the term "boat-tailed.". That bullet was found by T-Net member Thrillathahunt. I saved the photo for purely Eductional purposes, like this reply.

.50 BMG was introduced into service in 1921, it had been around a few years before that as a developmental cartridge but did not see common usage until them.

Keep looking around there and you might find some .50 cal casings with dates on them. My guess would be World War II era.
