This thread is an off-shoot of a thread regarding 8mm Floberts.
Jean-Pierre. I mentioned that I have several 6.5 mm Flobert rounds. From your response, you have not seen this round before. Sometime after the end of April I will post pictures of the rounds. However, the following is what I know about them.
There are a number of headstamped 6.5 mm Floberts. These include the raised TB headstamp, the impressed TB headstamp and a recently found KB impressed headstamp (which I don’t have). I also have 2 unheadstamped rounds. These are all extremely rare specimens and hardly ever turn up. It would appear that the most commonly encountered specimens have the raised and impressed TB headstamp.
The bullet diameter is 6.2 to 6.3 mm. The diameter is 6.3 to 6.75 above the rim. The rim Diameter is 7.4 to 7.5mm. Case lenght is 7.4mm on all of the rounds. This is a very distinct cartridge from the 6mm Flobert. However, if you are going through a junk box or looking over specimens on a table, they are easily overlooked (not that there are many on tables).
All of the rims are flat although all of the specimens have an early look about them which you will see when I eventually post some pictures.
Yesterday, I was able to have an xray done on the 8mm rimfire long copper case. It is indeed rimfire! So now we have two distinct case lengths in the 8mm Flobert: 1) the regular flobert specimens with the short case, and 2) the long case 8mm Flobert.
