Shot a box of three year old reloads just to see what would happen

[Fat Mike]

I had a box stored in a cool, dry place and figured I would test it. When I finally shot them, they performed exactly like fresh loads in every way I could measure. It showed me that properly stored components last a lot longer than most people think.

Cool storage definitely helps but I’d still be cautious before treating that as a universal rule for all old reloads.

I have reloads going back 30yrs or more. They still shoot the same as always.

I have not been reloading as long as @Frontiersman. However, I have ten year old reloads that are as good as new. I keep all of my ammo (factory and reloads) in 30 or 50 Cal ammo boxes. I may also toss in a desiccant pack for extra peace of mind. So far, so good.

Ive shot a few factory loads from the early 20th century that all went bang. I doubt they were doing anything back then we can’t do at home. I think protecting them from moisture and excessive heat are the important things. Those little capsules are sealed up pretty good if you load them properly.

Ammo-Factory or handloads have a LONG storage life if they stay in a cool + dry space.
My #1 Son trained with '40's-'50's ammo when He was in the 101st. in '96-2000'
These were surplus from WW-II and shot fine...Bill.

I found an entire tackle box full of 22LR when I was a kid. They were under water and had been for a long time. Of course I had to try and shoot them.

About 50% went “click”. The other 50% about half were audibly weak. Most had to be wiped off to chamber with effort. I’m amazed I didn’t get one stuck in the bore. I still have that rifle.

I have fired more than a few 19th century rounds. Many more early 20th century. Helping a friend use up all of grandpas old ammo. I would like to have those now.

As a general rule, I found if they turned green, they probably won’t fire. Otherwise, they will probably go off. Antique ammo is much better to collect than shoot.
