I guess COWW recipes have been covered pretty heavily but I know some people just go the route of buying "known lead" So thought it might be worth asking folks what alloys they buy and what recipes they use with those store bought beauties.
Useful information:
Alloy sources. Where you get the alloy.
caliber & maybe usage. E.G hunting, plinking, bowling pin, punching paper, bullseye etc.
Firearm type. Rifle, pistol, carbine.
Lube type might be of interest. Since PC can tend to allow softer alloy at higher velocities.
Maybe load or FPS type info.
I did some large batches of alloy mixed from scrap that I then had tested to get a home brewed Lyman #2. I use scrap yard plumbers ingots or soft sheet lead from xray shielding for "plain" lead. Probably not going to find much "pure" lead in scrap, but plain is close enough. The foundry Pb ingots I do find I hold back for muzzle loader and C&B revolver use.
I have bought or traded for lead and solder in S&S forum and made some purchases from Rotometal (a site sponsor, link at top of pages). At one time WW's from scrap yard cost as much or more than fluxed ingots of WW lead in S&S.
I use Lyman #2 to cast 70 grain .223 bullets that are PC lubed and driven at 2,000+ fps by approx. 24 grains of Varget.
Lyman #2 and plain lead mixed 50/50 I use for revolver rounds of .38 and .357 mostly mild plinking but some full power .357 mag with PC lube and gas check. Same mix with PC for mild plinking loads in old milsurp .308 or .303 British. Close to COWW and 1 to 2 percent tin in hardness or uses.
Most of my lead is from scrounging. I generally use COWW lead as an ingredient to make a known alloy. Keep some COWW ingots on hand same as a cook would keep flour. I included my recipes because one can buy Lyman #2 and plain that I use for these recipes from foundries.
