Watch out for the zinc ones mixed in those cheap buckets. Here in Toledo OH area the scrap yards were only paying about ten cents a pound for wheel weights a couple of weeks ago and fifteen for pure lead. JMHO but I would think the price of scrap wheel weights at the tire shops will go up as the complete ban approaches. The old supply and demand thing. Bill
Wireguy, Tire weights will only come to about 12 BN, hard cast bullets will usually run 20+ BN. IF you heat treat the tire weight cast bullets by quenching in cold water when their heated to about 500 deg. you can get the 20 BN.
I believe the receipe for Lyman #2/ Hardball is, and I am not positive without looking it up. 9 or 10 pounds of wheelweights to 1 pound of 50/50 solder.That is recepie Mike Venturino mentioned in an article once. The tin adds flowability and some more hardness to the alloy. Pure linotype is maybe 10 on the scale and it is more than hard enough for 1200 FPS. I don't plan on making bullets for 3000 FPS. Okay I got out the Saeco harness tester and the chart in with it says.
Pure lead= BHN 3-5 Saeco 0
Wheel Weights = BHN 9 Saeco 6
1:20 Tin/Lead= BHN 10 Saeco 6-7
Taracorp Magnum Lyman #2
1:1 Lead/Linotype= BHN 15 Saeco 8-9
Linotype BHN 22 Saeco 10
Monotype BHN 27-28 Saeco 10
From the Midway USA catalog:
Hardball is 2% Tin,6% Antimony,92% lead
Linotype is 4% Tin, 12% Antimony, 84% Lead
Go to "http://www.theantimonyman.com/thermometry.htm " for some more good info. So in answer to the question about hardening up some soft lead, Linotype would be what to use or maybe the right mix of some wheel weights by doing the math.Bill
