Excellent find ! I had a full 5 gal bucket of WW that has lasted me bout 5 years. I have about 45 lbs of smelted ingots left, and started to look around for WW's at the places I had scrounged from in years past......and that is the key......years past.
NOW, they are all selling to recyclers by contract, and will not/cannot give or sell any to me.....
I do have a good source of 22 LR [only] range lead, which cleans up to yield about 50% pure lead from the original weight. I can make 1:10 TIN/LEAD alloy using this and 50/50 solder which is supposed to come out around 11 BHN. [My #2 alloy BHN's around 15]. That should work well for GC, paper patched, and non magnum handgun bullets.....
I have not made any up yet, but I am hoping this will be a decent alternative to using WW that I can't seem to get any more.
