I would certainly use it for casting.

Melt it down in my 200lb outside WW setup, flux, and make ingots. Likely not as dirty as most of the WW I have melted. As far as arsenic, WWs have that also - major component for hardening, along with antimony.

Then a few test casts to see how much tin I need to add for fill out - perhaps figure out a ratio with WWs and Rotometal's Superhard for harder bullets as needed for things like 454C. Likely test hardness both air cooled and water quenched, compare to my stock of WW alloy as a reference point.

Back when I was a teenager, I was the first one into a local dirt pit after a rain. The water would wash away some of the sand and dirt, leaving the bullets resting a a short column of sand/dirt... easy to take a flat shovel and run along the ground, pick them up, dump through a home-made screen wire sieve, then melt down, removing jackets, rocks, etc. (Be Very Careful To Sort Out Any Unfire 22lr Ammo, or lead will go everywhere!) The alloy compostition was definitely unknown, yet it worked just fine in my 1911. Compared to that, shot would be really nice.

Check Rotometals for prices on alloys and even shot.
