CW bullets or not

[markp]

I'm not sure about these bullets I found today. I found one that resembles a Williams Cleaner bullet, but the weight is not right. It's diameter is .573 inches, but the weight is only 380.9 grains. It was found right in front of a big rock, and I'm sure it was shot into it. The next five I found was all small bullets found within a foot of each other. The first two weighed 245.1 and the other was 248.6 grains. There diameters are .467.5, and .469.5 inches. The first two lengths are .687 and.676 inches. The other three were made a little different and they weighed 242.8,240.9, and 242.5 grains and there diameters are .457,.455 and .454 inches with lengths of .699,.711, and .726 inches. Last but not least I found a cartridge case that is .350 inches in diameter and is .778 inches long with a U on the primer area. What stumps me is it is a rimfire cartridge, not centerfire. I posted it here because it seems more people look at this forum than What is this. Any help would be appreciated. I don't think the five small bullets are CW because of the vertical lines between the two rings on those five. I do think they are old, but not that old. I'm hoping someone knows more than me. I have found numerous CW artifacts in this area though. Thanks Mark

Your Bullets Are Not Civil War But Still Have Some Age To Them. The Shell Casing With The U Stamped On It Is A Union Metallic Cartridge Co. Manufactured Bullet And Is Probably From 1900-1930. Good Finds!

ATpro5 is right. Your bullets are considered modern.

Bullets with the little lines in the grooves are fairly modern. They were not used in early metallic cartridges or muzzle loaders. I put 'em right in the melting pot for fishing sinkers. The diameters are for a .45 caliber firearm, and most likely a pistol by the length. The casing if .350 outer diameter is a .32 rimfire short.

I think the brass case is a 38 short rim fire cartridge. It came out around 1865.

The multiple tiny parallel ridges in a bullet's body-groove are called "reeding." A bullet groove which has reeding is called a "knurled cannelure" by bullet manufacturers... but we diggers simply call it a reeded groove. According to the earliest documentation I've been able to find, reeded grooves first show up on bullets in America in 1878. See a late-1800s/early-1900s example in the photo below.

The single letter U as a cartridge-casing manufacturer's "headstamp" marking represents the Union Metallic Cartridge Company. Although that company started business in 1867, it did not use a headstamp until approximately 1877. From then until 1880 the marking was a raised letter U. From 1880 through '84, no marking. From 1885 to about 1920, the U was an indented letter... which is what's on the casing you found.

Thanks Cannonball Guy, your a wealth of information and I always enjoy your input. What about the smashed bullet? It looks like it has an insert. The insert is .573 inches and a weight of 380.9 grains. It was fired into a rock I believe, that's where I found it.
