Can someone help me identify this bullet?

[arobfeds21]

Hi all,

I'm new to metal detecting and really don't know anything about bullets. I found this in Northern Virginia near the Potomac River. Any help would be appreciated. It seems to have a few vertical lines going around it, as you can sort of see in the first photo. Appears to be filled with some sort of heavy cement/clay? I know nothing. Also, the bullet has a dent in it, a smooth circular dent.

Modern jacketed ammunition, lead gets that white/yellow corrosion when
it oxidizes.

Do a search for oxidized lead and click image search.

Looks to be .45 still has the rifling grooves at the base.

Did you find it at campsite? Close to a fire Pit?
Old burned out house?

Copper turns red when exposed to moisture and heat.

Modern but still old. Measurements would help a lot.

Based on comparing its size with your fingers, it appears to be a .45-caliber copper-jacketed lead bullet made for use in the Colt Model-1911 Automatic Pistol, but also used in the "Tommy Gun" and several other firearms. It is a fairly common 20th-Century bullet. There's no way to time-date it more closely, except that the lead showing in its base has been exposed to weather for enough years to thickly oxidize to a white-ish color (as Chiltepin indicated).

Thanks for the great information TheCannonballGuy and everyone else!

I don't think it would cement but it does look like oxidised lead on the inside. what is the diameter? It looks like a .45 it looks like a low velocity round.
