Fellow brought in to my friend's shop a Polish issued, Czech(?) mfg. 8xBIGmm caliber rifle to get sorted. Took a few quick pics, but I think I ought to ask permission to show them. Its 70"/1.78m OAL!
Does anyone have cartridge drawings, pics or specifications? Base is rather smaller than .50 BMG, probably about 0.640"/16.25mmInformation
