I picked up some lead today, hoping it is in fact 2-6-92 like it is stamped. It is hard and rings pretty good. Also got some more pure. 75 cents a pound plus tax.
Approximately 36 pounds (5 bars 2692at 7lb3oz per bar) for about $30.

It is stamped "2692" with as a single stamp. One bar weighed 7 lb 3.3 oz.

I am hoping some has purchased 2-6-92 in this form amd can verify it was consistent with what they have used.

I'm more curious where the heck you found it for that price!

No other markings on the ingot? Maybe a home mix rather than a commercial product?

XRF analysis would turn it from a hope into a certainty.

Treat it like it is! If the results aren’t what you expect after using it then send some off to be tested.

I purchased two ingots of pure lead from Midway and later upon further research the bars appear identical to the ones from Roto metals. Most likely Midway buys from Roto metals by the pallet or truckload. You could check those two websites and see if the ingots and markings match what you have?

First thing I checked was Rotometals website and a few other reloading/ casting supply sites. I haven't seen ingots like this yet.

I do plan to use as hardball (until it doesn't work)
I just have not had a chance to cast up some boolits yet. Thanks.

Is that 2% Tin and 6% Antimony? I see the elements arranged differently so many times that I never know which is which.

Same. There does not seem to be a set standard. Many listings put tin first as 2-6-92, but others list the Antimony first as 6%.

The 2-6-92 seems to be more common.

I figure these are from a commercial source based upon style of mold and the one piece 2692 stamping.

Or it could have been cast on Feb. 2nd 1992. Or it could be a stock number. You won't know for sure unless you have it tested.

You should test for hardness. If you don't have a tester, use fingernail test, pencil test, or ball bearing/vice test.

I really doubt it is a date or lot number, I mean could be but why bother putting a date or lot number without any sort of product description.

If it was a commercial operation then a lot number tells them everything they need to know, Useless to anyone else.

I would have paid what you paid and sure be hoping some caster mixed Linotype 50/50 with pure soft lead in their garage and poured those ingots. A near perfect alloy for a caster to do further work with at a later date. Add one pound of 50/50 solder to two of those 7.3 pound bars if they are 2-6-92 and you have pretty dang close to 5-5-90 or Lyman No2 with enough room in a 20 pound pot to flux. Cut that 50/50 again with pure for most handgun cartridges or use as is for higher velocity cartridges.

one other thing, I don't think it is a coincidence that the numbers add up to 100.

I have a strip of ingots just like that in my lead stash. they seem precisely made don’t recall any specific stampings but can check when I’m in there tomorrow.

And 2% tin /6% antimony is the composition of hardball alloy (1:1 Lead / Linotype)

I haven't had a chance to test them. I have a CabineTree, but think they are too wide to fit in the tester. I have been too busy to cast a boolit or melt off a piece for testing.

Strip I have is stamped 30-1 no makers marks just the same triangle between chunks.

Judging by the color of oxidation shown in photo and "It is hard and rings pretty good" and stamp/mark.
> then I am sure it's Hardball alloy.
.
What I like about hardball, is you can mix it 50-50 with pure lead and get COWW alloy.

I is it soft, might be 30 to one, lead to tin. Another common alloy.

When I first read " Is this going to be 2/6/92 I was thinking " Back to the future". :smile:

I purchased ingots from Midway 20 years ago like that. They had many different alloys that all looked like that. I purchased linotype, and mine had LINO stamped on them. I think you'll be OK assuming they are hardball alloy

Check your local scrap yard to see if they have an xrf gun and whether they'll test your sample (for free, of course)

Thank you, this is the information I was looking for. I still need to verify by sending a sample to BNE, or casting a boolit and testing hardness, but preliminary, just wanting to knownif anyone had purchased commercial ingots so marked, poured into such a unique ingot. Thanks.

No xrf close to me.
