Ever try VACUUM PACKING ammo?

In 2011, I sold over 400,000 rounds of .223 with SS109 bullets loaded and they were bulk packed in those bags - I never had a single problem or complaint.




Did you handload all of those ??

No... my slaves did

I got a box of 9mmx19 cases from a rummage sale. I tumbled them
pretty clean, and vacuum packed them in Food Saver bags.
Any handling at all, and the case rims cut the bags. I guess
I need some of Cat's thick bags.

Now I pack cases in freezer Zip-Lock bags, and pack ammo in
Berry's plastic ammo boxes, and pack those in MTM Dry boxes, or
old ammo cans. Never noticed any ammo degradation.

Thanks.

Ammo is fairly "air tight"... that is to say, if you load it in 50% humidity, it will stay that way, even in the jungles. If you handle it with wet hands, the water will not go in. If you drop it in water, leave it there for a while, and then take it out... it will still be fine and dry.

But, if you put it under a vacuum, the air in it will slowly be sucked out, leaving the case with abnormally low pressure in it.

Then, when you break the seal on the vacuum bag, the outside air will be very slowly sucked back in.

Now, if you open the bag in very bad conditions, and the cases are wet, or if a bag gets punctured while your back pack is wet... the water will be sucked in, instead of air.

Now, I'm not going to argue the odds of this happening, but you mentioned that water was a concern of yours...

... and my thought is why expose your ammo to an atmosphere exchange and the possibility of it "ingesting water", when it is not necessary in the first place.

I mean, sometimes we go overboard to prevent something and, instead, we bring on other problems that are worse than what we were concerned with in the first place. That's all.

I really don't see the need to vacuum seal ammo, but if a round were sealed such that humidity doesn't effect the powder in the round, as implied above, then it the light vacuum pressure wouldn't really have much effect on the round, and the chance of water being sucked in there would be very low.

To me if you want to vacuum pack ammo and you have a vacuum sealer (like the OP) then do as you please, but I wouldn't suggest going out and paying for a vacuum sealer. If the sealer Catshooter is talking about was inexpensive enough I would consider purchasing one of them if I wanted my ammo to be more immune to the elements than in a ziplock bag. Other wise I would probably just double ziplock the ammo and be done.
 
I processed brass about 5yrs ago all nice and shiny,vacuum sealed them and today they are just as shiny. I have also cleaned and vacuum sealed my muzzle loader and it works great,I cut the bags long so they can be resealed when you cut them open.
