Vacuum sealing ammunition

It absolutely can't hurt and it will keep them shiny. Why not?
I'll second the "Lose the box" recommendation. The corners place too much stress on the bags.

Seal away!

I was thinking of the same thing !

thanks krausb for the tip

on a totally unrelated note, any one see where i can get 5 inch PVC?
Home depot by me seems to only carry smaller stuff, but they do have nice shovels.

5 inch is a weird size, 6 inch is way more common. Your choices are electrical conduit, drainage, sewer or pressure service. The difference is mostly the wall thickness and colour. Emco or Worseley are big wholesalers or search for local IPEX distributors. Don't forget the end caps or proper cement and primer.

Real ammo cans just as AMET said. They were designed for long term storage, I have seen ammo come out an ammo can that was under water for 10 years that was just like from the factory

Before Covid, we conducted some ranges with ammo dated from 2002-2003 packed in those conveniant 100 rounds bandoleers (5.56x45). Everything was fine, no signs of corrosion.

If you've never been in an Army ammo depot, it is cold and damp. Most of us store our ammo way above those standards.

Get some real army ammo cans with a good seal, dump your ammo in there and there you go. Its ammo, don't overthink it. Label all the info on the outside to prevent opening it for no reasons and call it a day.
 
I suppose if you are at risk of a flood it might be some cheap insurance to vac pack your ammo. Otherwise it won't likely be of any benefit, because old ammo become useless when the primers become unstable and unreliable. This happens regardless if the cartridge is in air or vacuum. If you want to make it last 100 years instead of the usual 80 control the temperature, don't bother with the air.

Ontario goes from bone dry in the winter to near jungle in the summer. I presume from the great lakes. Its absurd the difference.

I agree with the near jungle summers, but bone dry in winter? Certainly not in the 20 or so winters I spent in it.

OK, bone dry is a slight exaggeration, but my basement gets down to close to 20%. Its dry
 
Weird. The other day I just happened to have some drying brass on a table beside my vacuum sealer and had the same thought/question pop into my brain. I was thinking about it from a different perspective though: vacuum sealing a couple individual mags-worth for my backpack to keep it dry, flat and more packable (i.e. in the big external pockets). At home it’s ammo cans and steel cabinets for me.

Thats a great idea actually. Will be doing that for sure.

I dont have a Princess Auto nearby nor do I really want to invest more money into this. I also went them to fit in my ammo safe.

Im not looking for ammo can advice. I am specifically looking for advice on vac sealing.

But I do thank you for the advice

Princess Auto has a deal now. Free shipping via a courier to your back door, no minimum price
 
you use a food saver to vacuum seal your game meat - why not the rounds? FWIW - i did this in 1996 with a roll of brand new pennies (remember them) today they look just as shiny and new. I re-use 1 pound powder containers and store my processed brass in them - nice and dark - all i need to do is to insert a primer and load - they look brand spanking new
 
Everybody seems to focus on the looks of vacuum sealed ammunition. What does putting your ammunition in a vacuum do to the velocity of the cartridges? When the cartridge is loaded the pressure inside the case is at or near 1 atmosphere. The moisture level in the powder is in equilibrium with the moisture level of the air around the powder. When the cartridge is put under vacuum the air pressure inside the case will eventually equilibrate with the air pressure in the bag. This will cause a slight drying of the powder and a possible change in velocity. Storing ammunition at atmospheric pressure would not alter the moisture level inside the case.

Finnally, I have no experience in this area. It is just a theoretical consideration for someone else to worry about.

Probably not a good Idea.
The vacuum process will likely suck the Air out off the Shell, then when the vacuum pack looses its vacuum (as they always do) Air or whatever the Shell is immersed in will be sucked back into the Shell.

Im not storing it in a lake lol

Im storing it in my safe, where it always is. Its not immersed in anything.
 
No one has mentioned collectible / valuable vintage boxes of ammunition. When you have a 100 year old box that is worth more than any rifle in your cabinet, may be worthwhile vacuum sealing the box for structural integrity, and preservation for future generations.
I do not own a vacuum sealer yet, but have considered it for the above reasons. Especially when you get into some of the old taped boxes in heavy calibers.

I have x25 packed since the 50's and x39 packed int the 60's- to the 90's, most was vac packed in metal containers, some you could still hear the suck of air when opened, stuff was all fresh as a stinky daisy!
