I hear all this hype about how great it is to have ammo sealed in battlepacks, but the prices in ammo, might not allow for all of us to have ammo in that condition. So my question is, is it adviseable to use those food vacuum sealers to store ammo long term?

Battle packs are not vacuum sealed, at least the ones that I've seen weren't.

I've vacuum packed ammo before. The bags will develope leaks over time, unless you cushion the sharp edges. Don't forget dessicant. Don't place it directly on the ammo, separate it slightly.

I hear it isn't necessary. I talked to someone once who said putting your ammo on a big bowel rolling it around as you add a few squirts of WD40 will prevent any corrosion if your ammo can leaks. He says all you really need is a waterproof ammo can, the WD40 is an extra layer of protection but is not necessary.

NOTE: Too much oil will cause many rifles to malfunction since it will dry onto the shells eventually, only apply a light coat if you do it at all.

Vacuum sealing is a waste of time. That is to protect things from air and water, all you need to do is protect it from water. Air doesn't hurt ammo unless it is like in a sauna.

DON'T use WD40 to protect your ammo. It will cause the primers to go dead.

NOOOOOO on the WD40.......

Makes for bad ammo...

brass cases will tarnish abit but not rust, wipe it off and shoot it...

steel cases well that's another situation...

If your worried about a real moist environment just alittle clear nail polish around the bullet case mouth and the primer socket should do it...

OK, so no WD.

I only have steel ammo for my MBR with the exception of 10 rounds. They are lacquered so they don't rust easy.

Put the nail polish on every round individually? Wouldn't that take an unholy amount of time?

Is that red stuff on Wolf Military Classic ammo nail polish? It is on the casing mouth and the primer edge.

I bought me an ammo can with a rubber seal on the lid, no water is getting in that thing until it rusts clean through.
I put in a few silica gel packets that were inside of a pack I bought, I figure even though they are used there probably isn't enough moisture in there for them to have much effect. They are better than nothing though, mostly just make me feel good.

I have never tried the WD, I just heard someone say that....he did mention not to get it on the primers if you could avoid it now that I recall. What does the WD actually do to them, the actual explosive is encased in the metal on the primer.

wolf ammo is already sealed on both ends.

Most american production ammo and normally reloads are not sealed on the ends, the reloads have a better chance of getting moisture in the case if unsealed.... It's a added procedure if you want somewhat of a ultimate ammo to put up type of thing....

Tha ammo can and silica gel is probally just fine.... Although keep in mind that the silica gel is there to suck the moisture that may form in the can out of it, once it gets full of whatever moisture that is in the can it won't do the job any longer so they should be replaced or repacked from time to time, of course were talking a long time though. The ammo can will keep moisture amoung other things out of the ammo in it but it won't keep all of the moisture out of it as moisture forms from condensation and therefore if the ammo can changes between drastic temperatures it will produce moisture from the air which was in the can when you closed it....

The primer pocket and the primer are seperate pieces, as the primer is pressed into the primer pocket of the case, so that means that there is always the chance that something can seep into the case at this point. WD40 isn't just oil, it is a oil compound that is designed to lubricate metals, and bond to thier surfaces, along with the ability to break down rust and crud so it will seep into the primer pockets by design, once there it will make the priming agent useless. It will also adhear to the casing and stay there, which will effect function of your firearms depending on whatever grit or temperature you break this ammo out in and have to use it.....

Oh I see now. I didn't understand how WD was penetrating the metal of the primer, it is actually going around it. Should have seen that before.

Thanks.
