lot of my bolt gun cast bullet cases come out looking like that too.
Which I why I mentioned holding back on adding the flashing. Good pure lead is getting harder to get these days, at least cheap stuff. I'd hang onto it myself.I'm just concerned that the extra lead in the melt will dilute the mix too much to the soft side, it's a waste having tin and antinomy in good qualities then soften it by adding too much lead.
I doubt the commercial caster will ever sell PC coated bullets, --- too labor-intensive for consistent results on a large scale BUT they have been selling HiTek coated bullets for over 25 years.On my pistol range we have a lot of commercial cast bullet shooters! So when I mine the berms I go though the trouble of sorting out the jacketed from the Commercial cast. Things like Shotgun slugs and HB wad cutters are culled also into a soft lead bucket.
I then smelt the Commercial cast into ingots, then the Jacketed and the soft lead into ingots! Lacking Clip on wheel weights any more I usually mix my alloys based on The Commercial cast bullet ingots and Jacketed / Soft ingots!
I get a nice alloy for wad cutters of BHN10 from 8 Lbs of Jacketed / soft ingots and 3 lbs of Commercial cast ingots!
However now that the commercial companies are selling PC coated bullets ....I'm not sure the are going their normal BHN 18 alloy so This is messing things up!
