So I was sitting there wondering about this while I was separating the lead from the jackets the other day, wondering if the jackets can now be re-used via swaging or turned into gas checks for other calibers.. Since I melted the lead out of the jackets, that means that the copper and in some cases brass (if they were montana gold bullets) were now annealed to a point (up to 800 degrees +) though not water quenched.. and needing a polish job. Would there be any use for these jacket shells or am I just better off scrapping the whole lot? Out of about 200 pounds of scrap range lead, I got about 20-25 pounds of jackets, give or take.
