    You sure it's not WCF?
  4. U.M.C .38 C.F.W.
  5. I think it means Center Fire Winchester, but I could be wrong.
  6. do you have any more dimentions? Maybe find some one to take a picture of it cause Im curious to see it
  7. .38-40 Winchester sound about right?
  8. Using a micrometer, from tip to base I got like 1.579" (1 19/32"?)
    Diameter of the base/rim is like 17/32" .
    Lead bullet, brass case and copper color primer.


    If photo's don't come out, I'll give it another try later.

    First is kind of hard to see because of the sun. Second is next to a pencil eraser just so you can get an idea of size.
  10. I didn't want to commit until I saw your pictures, but I'm thinking 4095 probably has it right :!:
  11. I would second or third that just form the looks.
  12. That is a 38-40 cartridge and is nothing more than a .44-40 case that has been sized down to accept a .38cal bullet. It was originally introduced by Winchester for use in the 1873 Winchester rifle. Chambering for the 1873 were .44-40, .38-40 and .32-20, at the time they were called 44WCF, 38WCF and 32WCF.

    During the old west the .38-40 was the third most popular cartridge for use in the Colt Single Action Army revolver, the .45LC was the go-to handgun round of the day followed by the 44-40 then the .38-40. Cowboys who wanted a handgun/rifle combo most often chose the 44-40 or 38-40 because the .45LC was not offered in a Winchester lever rifle until sometime around or after WW2.

    For a while the .38-40 had a small following among Cowboy Action Shooters, but the brass is thin and case life is low making it a poor choice for repeated reloading. Some of the more eccentric CAS guys still cling to the .38-40 but most prefer straight wall cases for reloading reasons.
  13. That definitely looks like the 10MM that won the West. ;)
