Vacuum Packed Primers

[robg]

i have vacuum packed loaded ammo ,didn't notice any difference to normal storage.if i lived on a boat i would though.

If it makes you feel better, go for it.

Personally, though, I think it's a waste of time and money. Primers are hard to kill. Normal temps and humidity levels aren't going to hurt them.

The vacuum sealing will not keep the vacuum for a long time. You are better off just leaving them in your closet on a shelf.

I have a sleeve of old 1960s Remington 69 shotgun primers that still pop, but very weakly, and the loaded shells are poopers. I don't know where they came from but the key is the flash holes are open to the air. Other, equally old shotgun primers with sealed holes fired normally.

The oldest of the "new" un nickled winchester pistol primers ( ~2003?) are tarnished but work fine.

All my nickle rifle primers, 1980 or earlier, are fine. Stored in upstairs closet. Near where the dog sleeps....just sayin.

Everything leaks eventually. Vacuum food storage is good because it deprives the food (and microbes) of air to slow the the deterioration. A vacuum is going to suck in air and moisture when it leaks, just not very much. It'll stop when the pressure equalizes.
The best long-term storage would be purged and sealed, that way when the seal breaks down there's still an inert gas in the container.
When I used to do a lot of camping/canoeing/hiking I used ziplock bags, double bags for the really important stuff.

Back after the New Town shooting it was near impossible to find anything reloading. I had never reloaded handgun ammo and had no SPPs. I found 2 boxes of remington SPPs on a table at the gun show. I asked how much and he said $50, so I asked for both? He said for all of them. I give him $50 and he puts 17 1000 count boxes in my bag. I notice the boxes look beat up, when i get home and look inside the boxes I notice they are damp and have very small droplets of water on them. I remember reading a story on Bench Rest Central about priming compound being water proof for many years. So i find and re read the article. The shooter puts 20 primers in 20 cases and puts 10 in a bucket of water for 30 days, them puts 10 in the window sill. When the 30 days are up he blows the water out of the cases and sets them in the same window sill. After a week he loads all and shoots through a chronograph and has 5 fps deviation. I took all my primers and opened all the packaging and put all the little trays and all the paper boxes in the dehydrator for 2 hours. I have never had a misfire with any of them yet. I think the writer on BRC had good information and don't think moisture is the problem it was years ago.

I think you're right. I don't vacuum seal anything, I handle my primers with my bare fingertips, been doing it that way for a long time. I do store my powders and primers in a small refrigerator but I don't think it's really necessary - just a thing I started doing. If they're dry when you load them they should be fine. If I was hauling primers and powder out to the camp site I'd double bag them but wouldn't bother with the vacuum.

I reload at camp to target shoot there. We are there off and on year round not just for hunting. I keep a full reloading set-up there. Press, dies, bullets, powder and primers for all calibers I own to save hauling things back and forth. Keep clothes, food, fishing gear, etc. Everything I might need so I can jump in the truck and just show up

I live in wet humid Louisiana. A couple of weeks ago I discovered 5,000 Winchester small pistol primers, 2,000 herters large pistol primers, and 2,000 CCI shotgun primers stored in a box in my reloading room. I bought these primers back in the 1960's. They were stored in the attic at my Fathers house where daily humidity goes from 100% down to about 50% daily. The temp in the attic would go from 150 summer day to about 30 winter night. These primers still work fine. There is no need for special storage conditions for primers.

I have used some of my dads primers from the 1970's with no special storage and no issues.
