Zinc Alloy Z-bullets

[Leadmine]

I was looking at National Boolits Catolog and notice they have Z-Bullets, which are listed as a zinc alloy boolit. Does anyone have any xperience with these? What does the alloy consist of? Has anyone tried to cast a similar boolit?

If I remember right ,I read the Z bullets are zink plated like the copper washed bullets.

Never tryed them.

I have heard that zink is a SOB to get out of a barrel
