With scrap I could contemplate trying to pack it all into a little
pint-size can, without having to melt it down or do too much cutting.
^^^^^^^^^^^^^^^^^^^^
The reason people are suggesting a solid billet is that no matter how you
try, you will not get the spaces out from between the pieces of scrap. You
lose average density due to the little spaces between the pieces. You
probably won't come out ahead of solid lead pured into the can.
Maybe you could fill the can as full as possible with scrap tungsten or
uranium, and then pour molten lead into the spaces.

Mercury might do and it's easy to melt but not so easy to machine!
White metal might be your best bet.

Mercury is cool, a little denser than lead but not much. In my town,
though, if you drop a thermometer you get a hazmat squadron showing
up.

"White metal" I think will always be less dense than lead. It might
have lead but it has other less dense metals too, right?
In previous jobs I got to play with not just lead but also tungsten
bricks.

circa 8 kg per pint, not quite the desired 10.
Iridium and osmium would meet the spec of >10 kg/pint but they're a
bit pricey -- around $400/troy oz. 10kg is 321 troy oz, about
$128,400 worth. Still, it's heavier than gold at less than half the
price, heckuva deal!
