Yeah, but in Australia goats are seven feet tall, and weigh two hundred and fifty kilos.
They also have four inch fangs, and are highly poisonous.
Not to mention they have opposable thumbs (for opening doors) and a bad attitude.
They are marsupials, as well.

What kind of total impulse could you get with 15 foot long 54mm case?

I don't know, but I'd love it if it's cored only a third of the up or less, and end burns the rest of the way. (I'm riding the back of a car or I'd calculate an estimate by scaling up in length from a big real 54 mm motor.)
