Properly loaded, primed, crimped ammuntion is airtight already. Vacuum packing is gilding the lily for the internal ballistics.

Keeping the brass cases from tarninshing is another matter. If your ammo is expected to be exposed to caustic substances (ammonia, salt air, high humidity, etc.) sealing in zip-lock bags, heat-sealed bags, airtight containers (military ammo boxes or Tupperware-like containers) or vacuum-sealed bags would be my desire (and in that order of increasing security and doubling up if maybe - e.g. vacuum sealed bags inside airtight ammo boxes)

Generally not worth the trouble. Keep your ammo dry, cool and in humidity always lower than the dew point and you will be good for a very very long time.
