These FMJ bullets made by Pretoria Metal Pressings are jacketed with a gilding alloy of 95% copper and 5% zinc.    Okay... stupid question time.  Is this alloy safe for use in our barrels?  For all I know, this may be a common alloy used in many jacketed bullets, but I want to make sure that I don't significantly reduce the life of my barrel if 5% zinc is known to have any bad effects.
