First Post: Where would this lead have come from?

[Recruit]

Ok hotshots...it took all of 34 minutes from my original post for someone to figure out that I had duck decoy lead. Mighty impressive I would say!

So here is another batch I picked up from the scrap yard today at 75 cents a pound. The owner had no idea where they would have been sourced from. Each plate is 12 3/4" long, 6 1/2" wide and 1/4" thick and weigh 7 pounds. I picked up 8 of them and they are all cut and drilled the same as the one in the pic. Any ideas?

Counterweight

You have to make it harder

Good grief cdngunner; 15 minutes? My hat is off to you!

Counterweight from what? Also "make it harder" as in this stuff is pure lead?

[cdngunner]

As in the questions should be harder.

Could be a counter weight for almost anything

The fact that they were all drilled the same and cut the same means they were probably stacked at one point

This lead is probably an unknown, if I was making one I would use the cheapest scrap i could find.

Ha!..went right over my head

I had a counter weight that was 5 slabs that was tested with an xrf gun. Turned out to be 5.56 antimony .75 tin with a touch of a arsenic at .35 so essentially really high end COWW.

Could be almost anything but you might try using the pencil test described in the sticky. What you mostly need to know is it hard enough to use for the bullets plan to make. Too hard/soft throw in some something known that will push it in the direction you need it to go.

Best bet is to get scrap yard to gun it and tell you exactly what it is.

Yep, was at Staples and Officemax yesterday looking for the Staedler Mars Lumograph set and struck out. Guess will have to buy online.

Unfortunately, the scrap yard guy didn't have a tester.
