I shot a case of WWII surplus 45 ACP a few years ago, sealed in a spam can. It was all headstamped 42-43. Ever single round in the case went bang; it was well over 60 years old. Brass reloads real good too!
I have had zero duds on the 1970's era primers; several thousand shot. I shot all of the large rifle and almost all of the small pistol primers now.
I'm down to a couple boxes of the large pistol magnum. My uncle had one of those 357 maximums... hand cannon - I use those primers for shooting rubber bullets in the basement. Also have about 700 of the small pistol primers.
Archangel;
I inherited these from my Uncle, so don't have a date on when he bought the primers. He bought them at some point between the time he got back from Vietnam, and quit loading in 1994 (have his handloads in a crate; last load date was in 1994). He didn't load any ammo the last few years of his life; he passed away in 2000.
Which leaves almost a 25 year window.
