Since the insanity of late it seems that small and large pistol primers are unobtanium . So I was wondering . If Federal primers are known for being soft ( as per warnings on Lee Hand Primer ) , would Federal small rifle primers work in a pistol round . A buddy had told me that it would work a while back so I grabbed some Sellior & Belloit small rifle primers . About one out of three would fire . Like a dope I did not thoroughly check it out before loading . Also if anyone one knows where there might be a deposit of unobtanium where a lowly pistol shooter like myself could find small pistol primers I'd be much obliged .
