Experimental military cartridge from late 50’s to early 1960’s from Denmark made by reforming existing 30-06 brass. It was loaded by Dansk Ammunitionsfabrik A/S because it is shown in a loading table made by them sometime after 1955. Not much is known of the rifle used, but there is a picture of the Madsen DISA carbine. The other pics are from a Madsen LMG that was featured in a Rock Island Auction a while ago. It is in all probability not the 7×36 as the magazine looks like it fits a larger cartridge than the 7×36.
