I saw a LOC Magnum (not very high, 100 or 200 feet) fly on a Vulcan
H-300 at one of Ross Dunton's launches. This happened a couple of years
ago and we all we impressed in one way or another.

When I was a kid we used to see how big of a rocket we could launch
with the smallest motor. We wanted to see how low we could get our
rockets while safely recovering them. For example, a Big Bertha and a
1/2A6-2. (I don't remember if this combination worked, but that's what
we had in mind)

That LOC Magnum launch was just like old-times...

I have flown my Bruiser on an H242, and my Magnum on H112 and H450....
you have to use a timer or altimeter to get the chute out fast, as 2-3
second delays aren't available.

I like that idea :-)

I remember very well what happened when I tried to launch a Big Bertha on
that very motor, in about 1972: it got just high enough to fall off the
rod, drop back to Earth fins-first, and breat off a fin before ejecting.

On an A8-3, it went up about 50 feet, and ejected coming down, at an
altitude of not more than 15 feet, perhaps less than 10.

I'd have to say the A8-3 is the smallest motor the Bertha will fly safely
on.  And no, it doesn't do at all well with an A10-0T CHAD staged to an
A3-4T in an adapter.

Souunds a bit marginal to me. I've seen a Magnum flown on a "no longer easy
access" I357. I wouldn't recommend less.

The Vulcan H300 is a full H, as I recall, and the I357 at 360 N-sec if I
remember right is an I by courtesy only.  I don't think there'd be much
difference between the two.

Hey Bob, when is this bug up your ass going to die?

Shouldn't this be "no longer easy access after 1997"?!?

I guess we're both wrong. It seems that the BATF has declared that "easy
access" never had any basis in reality. They are aparantly giving us till
the end of the year to dispose of our stock.

I should have said "never really was easy access"...

No, they are giving us until the end of the year to get a LEUP and some
sort of approved storage.  It's only if we decided not to get a LEUP and
some sort of approved storage that you would need to dispose of your
stock.  I see no problem with a Section or Prefecture getting the LEUP
and magazine, and possibly also becoming dealers.
