Unknown (to me) 20mm - .50 cartridge -> Name & Dimensions?


Can anyone give me informations on this cartridge (Name, Dimensions, current dev. stat.) -> http://www.snipershide.com/forum/ubbthreads.php?ubb=showflat&Number=1573251

THX a lot,


I can’t give you any good details, but it’s a 20x102 case shortened and necked down to 50cal
"Modernized" 50/60HMG kind of thing?


Hi Tailgunner,

I mean the “other” 20mm - 50. ;-)

Your pic shows the 20-50 Anzio -> http://www.anzioironworks.com/Anzio-20-50.html



I “borrowed” the first 50-20mm photo on the thread you posted. Sorry if it was the wrong one.
