I'm not sure where to ask this. If I have it in the wrong place please move it..
I had my vacuum sealer out for some Canadian bacon I made and got to thinking, what about storing ammo this way long term?? So I took a hand full of freshly cast, powder coated boolit clad reloads and put them in a bag and sealed them up. Has anyone done this? Does it cause any issues with primers or powder long term? All the surplus ammo I've ever had in sealed cans seem to have just a bit of pressure in the can when opening. You get that lovely hint of (7.62X39) 50 plus year old Chinese air wafting out when you first poke a hole in the can. What about ammo stored under vacuum instead of pressure?
