Re: Lead Shot
> use 'boiler punchings' ...Once upon a time, I actually saw an ad for 'boiler punchings' sold by
a scrap dealer in the Baltimore area (as best I remember) especially
for ballast use. I wouldn't know where to go for them nowadays.
Or for sections of used rail, either.

FYI . . .
The shot sizes most prevalent are for the clay target shooters who
reload; #'s 7-1/2, 8, and 9. At these sizes they all 'flow' like water,
especially the smallest - #9's. {there are about 400 pellets in a 1/2
ounce .410 Skeet load}. I really wouldn't worry about 'random packing'
formula's or any mass calculation other than the simple cu.ft. density
of lead. Shot for reloading is generally sold in 25 pound bags. They are
about the size of a man's calf, which should give an idea of the volume.
Personally, I have better uses for high grade shot. DON'T EVEN think of
using it 'plain'. It flows like a liquid, and it's like trying to pick
up the same with your hands if it spills . . . I definitely wouldn't
want it in MY bilge. Cast it into 'pigs' by mixing it with Resin {here I
WOULD use polyester}, or cement. My preference would be to use George
Buleher's {?} advice . . . use 'boiler punchings' {or wheel weights}.
Probably such a small lessening in density wouldn't matter for the
purpose under discussion.
