Vacuum Packing Ammo?
Is it safe to vacuum pack ammo. I have one of those food sealers, and have thought about vacuum packing the extra rounds I carry in my pack. But when you pack marshmallows, they expand to about 5 times their original size. I wondered if anyone knows about ammo? I thought I saw some .223 ammo at a gun show packed, but wanted to ask before I did it. Thanks
