Zinc will have less barrel friction than jacket metal, so you should get lower pressure than the same weight jacketed bullet in spite of the longer bearing area due to the lower density of the zinc. Wow, this might be the way of the future. If lead becomes illegal, at least we would be able to shoot with zinc bullets.

For example, Zinc coating on steel prevents galvanic corrosion of steel. Even damaged sacial coating continues to protect the base material. The extent of corrosion protection depends on coating material and thickness. For example, 12-micron zinc plating will provide more corrosion resistance compared to 8-micron coating.

Zinc Serves as a Sacial Coating. Interestingly, another reason that zinc coating is so effective at stopping corrosion is due to zinc's own corrosive properties. Through a process known as galvanic corrosion, zinc will "defer" to the metal that it's protecting. Zinc is more electrochemically active than iron.

Abstract. Zinc coatings exhibit different properties, which depend upon the composition, microstructure, and morphology of the overlay that make up the bulk of the coating. Galvanized coatings contain less than 1% Al and form spangles that result from the dendritic solidification of Zn. Galfan coatings (5% Al) consist predominantly of a ...
