As far as I know, it doesn't makes any difference how fine the shot

the same. Of course if they settle better...

only wanted another way to guess the number of spherical chocolates

I'll find out tomorrow how close I came.
No Bolger content to speak of, but if I win the chocolates, I'll take
them for treats on my Christmas sail on my bolger Chebacco.

Since the advent of steel shot I have become proficient at making
lead shot. Tungsten carbide powder is not as dense as lead. The only
thing denser than lead that can be handled safely is gold. I use
tungsten carbide to re-sharpen my rock core drill when I have to test
soil samples.
All you have to do is melt the lead and pour it through a screen
into a bucket of soluble oil. All the lead has to fall is 6" to 10"
because after it comes from the screen the lead forms a perfect
sphere or shot. The smaller the screen the smaller the finished shot.
Since I liked to break clay pigeons I used finer shot but you can
make the shot as fine as you like. The finer the shot the less space
between the shot and the more weight you can carry. I suppose a whole
bunch of lead and epoxy is more expensive than just lead but I
suggest a small length of railroad iron would be much less expensive.
Unlike lead and epoxy there is no long lasting bodily effects when
using rail unless you drop it on yourself IMHO.

Before you give up on melting
lead, grab an old pot and
put it on a camp stove and
try it! It is really easy.
Another more dense option
is to cast 'pigs' by pouring
20 lbs of lead into an old
bread pan. Certainly much
denser that lead shot.
Embed the pigs in epoxy
instead of the lead shot.

Hi Jamie,
I used lead shot for the centerboard weight when building my Bobcat. I
used the same cutout which was supposed to carry 20# of lead. The shot
I used came out to about 15#. It was necessary to do a lot of stirring
to get the shot settled down in the void.

Jamie - My Micro keel shot-packed considerable less than I had
calculated. The additional area I allowed still wasn't enough, and I
had to add a steel shoe on the bottom.
I don't remember the packing ratio I anticipated, but it didn't
happen. Seems like I got maybe 50% (?) Were I to do it again, I'd
fill a jar with shot and weigh it (if you do, let us know the result).
I also poured in a lot of thick polyester resin - probably affected
the fit of the shot. I think I would also thin the resin with a lot
of acetone.

About 64% density.
http://mathworld.wolfram.com/RandomClosePacking.html
You could verify with by weighing a cubic inch or so of lead shot and
comparing that with the know density of lead.
