Ammo Help ID this bullet

[DixieRifles]

Somebody found this bullet and I dont know what type it is. I saw the first photo and guessed a Sharps. The base is flat and appears to have a design— not like a cleaning round.

I dont have it so I cant get any dimension.

Looks like a Spencer

I get my Sharps and Spencer bullets confused.
Photos of most Spencer bullets show 2 large rings. The one in photo has 1 and maybe 1 smeared into the base.

Looks like a .50 cal. Warner or .50/.56 cal. Colt revolving rifle bullet.

Caliber size would greatly assist.

I think you are right on being a Colt as the cast seam says Colt.

Okay. That would seem fairly conclusive.

.50/.56 cal. Colt revolving rifle bullet.

Oh! Wow!
That would be great. If it WAS found here in town, there is documentation that Colt revolving rifles were used by 2d Iowa Cavalry in a battle.

I noticed the mold seam. That threw me off.
