8mm Lebel Gallery or Short range?
Here is a possibility, from the old 8lebel.org forum:
Nice variant. I have never seen the variant with the groove below the ball.
Yes, Thank you. What you post is all I have knowledge of.
I have done much searching before posting here to no avail. Round is still a mystery to me.
It is a cartridge for short-range shooting training, with the particularity to be reloaded (uncrimped primer) in the troop corps. Normally, the 8.45mm lead bullet is self-supporting in the collar. It sometimes happened that she sinks too much when reloading, the collar being a little too wide. That’s why it was added a groove on these cases. A nice variation.
