Leading to a malfunctioning , allowing the ignition before the breech was 100% closed .
All this is guess work . Take it for what is is or is not worth .
Best I remember reading , the bag charges contain a small amount of black powder at one end . Black powder being easier to ignite than smokeless , I am told .
So , the bags were positioned with the BP end close to the igniter . Which sets off the BP , which sets off the smokeless powder in the bag . Which sets off the other bags .
As to the OP's original question . As has been stated , it all depends on how the ammo has been stored . Ammo does not " like " hot climates , or damp / wet climates .
I have some .30-06 FA ammo from WWII . Sired some in a Garand . Some were fine . First one that had a case separation ( no harm to me or the Garand ) , I stopped shooting that ammo . If I should ever fire it , it would be in a 03A3 bolt gun .

Different powder.
Different circumstance.
Iowa had loaded the shell, and was loading individual bags of powder in the breech. The powder was well past its expiration, separate, and out in the open. The Iowa's powder went bang with the appropriate force, but at the very wrong time. The OP's ammo is contained within the brass, and not going to get sparked by mishandling. It'll go bang at the proper time.
I ran into a guy who calls himself "Battleship Mike" and he was aboard the IOWA during the explosion. He has more more recently done volunteer work on the IOWA maintaining it. He said it was over-ram that caused the explosion.
The guns were also overcharged several times, against regulation. It's been a while since I learned about it, but I believe there were several contributing factors
