A question about original 56-56 ammunition types

[Jim W]

Team,

I have picked up a few different rounds along the way, and wondered if anyone here could answer a question. The first 2 have an "H" headstamp; and look the same, the second 2 have the "U" headstamp and look the same. The third has the same "U" headstamp, but is a bit longer, and tapered, but not bottlenecked.

I believe it is a Spencer round; is it a later one?

Thanks for any input!

The "H" head stamp is for the old Henry (Winchester) made ammo.
The "U" head stamp is for the Union Metalic Cartridge CO. which will become Remington (Remington/Peters) made ammo.
Without knowing the dia. of the bullet in the 5th cartridge you pictured compared to the other 4, it would be difficult to say which firearm this round was made for. Perhaps, Spencer's designed 56-52, but, it should be basically the same overall length as the other cartridges made for Spencer actions.
My best,

I tend to think the longer one is 56-52 as well.

Am I correct that the Henry ones are newer (post Civil War) and the Union Metallic Cartridge ones are Civil War era?

Jim W,

The longer cartridge maybe for one of several single shot rifles/carbines like Ballard or Joslin. Just a thought on my part?

The head stamps were used both during and post CW. At least for as long as the ammo was being manufactured.
The "H" head stamp will change from the imbedded "H" stamp to the raised "H" (like in the 2nd cart.) as time went on.
I hope this helps?
My best,
Blair
