Found bullet, need help

[bazzelle]

Hello all,

Found this bullet this past weekend. I'm thinking it is a 54 cal carbine. Not sure exactly what it is though. Can some one please help me identify what type of bullet it is.
Best measurements I can get are 10mm at base and about 18mm long. Please let me know if any additional information is needed.

Thank you.

Well... in your photos showing a millimeter ruler, the bullet appears to measure about 11 millimeters in diameter ...which is approximately correct for a .44-caliber lead bullet. Judging by that and your bullet's overall form, the closest match would seem to be a civil war era .44-caliber Colt "early-model" bullet, made for use in a Colt Army revolver. Compare one of that kind in the photo below with your bullet.

Note, you said your bullet is 10mm wide at its base, but it gets a bit wider than that at the top of its "rebated" base. So I think 11mm is about right for its main-body diameter. Also, there is a .44 Colt "early-model" bullet which is .770" long, and that is quite close to the approximately 18mm length you report for your bullet. See bullets #488 and #489 in the McKee-&-Mason book on civil war bullets.

Just the information I was looking for. It's my first bullet finding and now I have a new book I need to find. Once again, thank you for the answer and info.
