Dwm 431l


I have in my collection a 6.5x61mm cartridge with the DWM K K 431L h/s
It is fitted with a gm fmj projectile. According to my information it is a
6.5mm Swedish, 61mm case length for “Torpedo” bullet.
Does anyone have any more information? Is this a military experimental?


Curtis Steinhauer’s list of DWM case nos. show the 431L as a 6.7x61 Swedish, but I can’t say I’ve ever heard of it before.



It may have started as an experimental military round but it is more commonly known as a sporting cartridge. According to Dixon, it was produced as sporting ammunition by DWM from the early 1920
