Primed brass that sat?

Nope. I size and prime my brass and then store till I want to finish the loading. I have some that has been stored in clear plastic jugs for a couple years before loading. Never had a problem.

 

Primers stored inside the home should be fully good for many decades.

You do know that primers (like Winchester) are not packaged in sealed containers at all. It is a paper box with the primers laying in a plastic tray, fully exposed to the air.

No problems here. I have over 200 rds. of 30 carbine thats been sitting in a plastic coffiee can for 8 years primed and i load a few here and there and they shoot just fine.

 

i usually clean and size a few hundred pieces of brass per setting. out of those. i baggy them up in 50 round packs.

I make sure I have 50 primed and ready to go in each caliber I load for.

that way if I need to load some up quick one day.. i just grab my pre-primed baggie and start charging..e tc.

never had an issue.

 

I store mine in locking lid totes.
Think about it, how are they pkg. on the shelves?

 

yeppers, they're good to go. I do keep mine in ziplocks just as a backup but I figured since the manufacturer didn't feel it necessary to package them sealed, they must be individually good to hook against the moisture in the air. I do it in case of accidental spill and my garage is not insulated or heated so there's a chance of condensation.

I've had some laying around in primer trays or on the primer spillover on my Dillon for looooong time; eventually they get loaded and all go bang.

matter of fact, I bought a brick of Winchester shotgun primers a few weeks back and left them in the back of my truck (just tossed them in my empty hulls mesh bag) and was inside for 3 hours, unbeknownst to me it started raining. Didn't realise it until about 2 hours of hard rain had happened, just let them air dry and they worked fine. Didn't get submersed, but the cardboard was saturated for sure.

 

you're good to go with those 'old' primers.They'll work fine.
