Hi,Need some help,I have come across a quantity of this ammunition,But never seen it before.
They all look like they were live and then fired and reloaded and made into drill rounds.
They are all wartime dated 43,Headstamps look American,LC TW SL and DM.
The cases measure 12mm diameter around the base,8.5mm around the neck and have an overall case length of 51mm.
Thanks for looking.
