50# Lead Counterweights... possibly. Anyone seen these before?

[IPSick]

Can someone throw this in the calculator for me, I'm mobile right now. Tha ks!!

U DUN GUD!! BUY ALL YOU CAN!

Basic Rules for Hardening Lead-

For every 1% additional tin, Brinell hardness increases 0.3.
For every 1% additional antimony, Brinell hardness increases 0.9.
For a simple equation,
Brinell = 8.60 + ( 0.29 * Tin ) + ( 0.92 * Antimony )

Here is the formula from the rotometals site you use the 8.6 for pure lead.this is from the hardness cuve being a lot steeper up to 8.6Bhn.after 8.6 the curve flattens out.so it would be 3.54x.92=3.25 and .37x.29=.1.then the formula 8.6+3.25SB+.1Sn=11.95Bhn

I have found this formula to work very well for what we need.I think is is what the alloy calculator found here is based on.

I do not know what you are going to cast for but if you add1% to 2% tin for better mold fillout it would make a great all around alloy.Adding 2% tin would make a 12.5 Bhn alloy.Man you better go buy all of that stuff you can afford.And get to casing some Boolits.

3 parts lino-type to 1 part lead will give you super close to your picture there, only with about 1/2% more tin.
no calculator needed for that math.

Ain't that essentially old time good COWW lead? .5 Sn and 3-4 Sb is essentially COWW lead. This is what the alloy calculator uses for COWW lead.

When lead deals come along like this.....take it because its going to be a long time be for another comes along


My was in 2009 about 2500 lbs of this content


Since then another in 2011 of 2100lbs. It been dry and no lead since.

I totally agree, I recently did a swap for 450 lbs of dimensional Lead. I don't really need any more, and didn't want to lay out the cash, but it maybe years before I get that opportunity again. But that is tough to sell a newbie (like the OP), who hasn't cast any boolits yet, who is just thinking of getting started, to buy a large batch of Lead.

Well, the gun was on loan to their other yard too far for me to drive. The guy thinks is pure, but couldn't tell me for sure without the gun.

Ended up scraping 'cause this Has just become a huge pain in my ***.

But saw this while I was there. They wouldn't sell any brass to me due to company policy; and worse to know they melt it down.

I literally laughed out loud when I read this. Well done. 10/10.

Add a half pound of pewter for

Tin %	Antimony %	Arsenic %	Copper %	Silver %	Lead %	Weight	Est. Hardness
4.76%	3.66%	0.00%	0.07%	0.00%	91.5%	10.5	13.3

Or a half pound of "Silver solder"(96% tin 4% silver)

Tin %	Antimony %	Arsenic %	Copper %	Silver %	Lead %	Weight	Est. Hardness
4.92%	3.37%	0.00%	0.00%	0.19%	91.5%	10.5	13.1

That last close-up picture looks like they have hard edges…notice the top beveled edge…and I don't see the typical dents and whatnot associated with a large soft chunk of lead that has been kicking around for some time. Except for the dark one the others look splotchy as if they had a large content of zink. Take some pencils with you and give them the old pencil scratch test ( Look it up on You Tube for a quick tutoring )
Tell us what they are…OS OK

ROLMAO, I have heard. I have not been there for a long time but is this what is has come to there?

[ccjcc81]

How much does it cost to have lead tested like that?

[lightman]

Many scrap yards will do it,some for free. A member on here offers a test for a pound of lead.

[ccjcc81]

Good, thanks.

[IPSick]

Take these with you for a quick test:

Attachment 156174

Those are only good for testing lead in paint and other such elements.

Between south/west CV, El Cajon, and East side of downtown... pretty much.

I got mine tested for free at a local metal recycling plant.

On to the next haul.

Found some KEEL lead. Owner doesn't know the content. Should I roll the dice? I'm feeling like a complete dummy for not jumping on the trolley weights.

Read the sticky on Art Pencil for hardness testing. Provides a quick and dirty check for hardness. After all the alloy composition is a means to an end, that end is hardness appropriate to the bullet being cast. Hardball and Lyman #2 are totally different alloys but same hardness. If that keel is dead soft then you know it will take something to harden it.

I have to say even if you don't want to sell it you probably should consider the sale price when evaluating the "value" of the lead you are considering purchase of. If you are getting lead that has a cost in the market here of $1 a pound and you can purchase for 45 cents that translates into darn good deal. Even if you don't sell for that price difference, the difference reflects "value".
