Have a question on the 7MM Super Mag .I have run into a E Arthur Brown single shot falling block pistol chambered in this .The question is the seller knows nothing about it and just wants to sell it(estate) ,no dies, no brass .I am guessing it is mid 80s vintage /also has a pachymar dominator for sale too 308win but no interest but figures to about the same era
So what case is it based off for the 7mm super mag ?
did more google and found it ,looks to be 357 max case or 5.6x50R and wow SHORT NECK form pics
