The message om
from "Dave Liquorice" contains these words:

Care to look at you units?

I saw a website about power stations a few days ago proudly claiming
outputs in the order of hundreds of milliwatts.

And this bunch, who really ought to know better since they're in the
business of explosive devices seem confused about Joules. I suspect it
would be hard to make an explosive device that liberated only 6 to 9
milliJoules. A mistake repeated through the document.

Nice toys though. But alarming when you read
"The slug impacts with approx 13 - 15mj energy that is accurate
to at least 60 metres. A free-fired BD 318 could result in
the slug traveling more than 5 kilometres."
