a friend showed me a gtg. he found in is grandfathers possessions. his grandfather was a WWI Vet and died in the 60's. The ctg. is based on the 30 US Govt. (30-40 Krag) and is necked down. The headstamp is 236 USN. The only thing I can think of is it was an experimental round back when the Navy was testing for a new ctg. and decided on the 6mm lee Navy.

  Thanks HRF, this one is the rimmed version. If he finds a second one I will get it and post photos.
  
  There was a considerable amount of experimentation with the .236/6mm cartridges in the 1890s. I mention and give specs for the rimmed .236 USN, rimless 6mm USN, rimmed .236 Remington, rimmed .236 Luger, rimless 6mm Luger and rimless 6mm Mauser in my Winchester Lee book on p.20.
  
  Remington was late to the party in the 1890s ( as they were in the 1950s) in developing the 6mm and so far the only rifle found chambered for the .236 Remington was the 1896 New Model Small Bore Rollling Block. The 1899 Remington Lee sporting rifle was chambered for the 6mm USN. The .236 Remington cartridge is a hard one for the collectors to find. The rifle is very rare.
  
  There is some confusion as the original rimmed US Navy cartridge was called the .236 USN and it was used for trials with the last production in April 1895. Some of the Winchester Lee sporters are stamped .236 but they take the rimless 6mm USN.

  Winchester manufactured a small number of Model 1885 Single Shot (high-walls) rifles in 236 USN. At least six of them were sent to the Indian Head testing facility in 1896 for evaluation. I will have to look it up in my notes for the total number that were made.

  Maybe Bert can find this, but I think Winchester offered ammunition in both a rimmed and rimless version of the 236 USN for a couple of years.. When the Navy finalized a rimless version ( actually a semi-rimless ), it was known as the 6mm Lee Navy..
