I'm aware that once the cans were opened and the ammunition loaded, the iron would corrode fast, but perhaps that would be acceptable to the Vatican-backed hunters if it meant that the bullets were totally pure cold-forged iron and that no jacket of other materials interfered with the delivery of iron to their supernatural foes.
Yup, that should work as long as, during storage, the iron has direct electrical contact with the zinc. Even after the case is opened, as long as you put unspent rounds back in the case so that the iron is touching the zinc, or so that the iron is touching a conductor that is touching the zinc (say, the brass case), you should be fine.

In fact, you could galvanize the inside of the brass shell. Although that might lead o weird chemistry where the oxidized zinc chemically reacted with your powder. Maybe put the sacrificial zinc electrode on the back of the shell.

Going by Anaraxes' suggestions, oiling the iron usually helps quite a bit, and storage in oil is an excellent method of preventing corrosion.
