What was the most nose weight you ever saw in a nosecone and what size nose cone was it? I need what seems will be quite a bit.
I helped load a 10" Saturn V on the pad once and carried the capsule part out. I don't remember exactly, but I thought they said they had around 25 lbs of lead shot in the nose cone. All I know is it was very heavy lugging that thing 500 ft out to the away cell.

I've heard of someone putting 3 bowling balls in their nose cone on an O motor flight.

What size is your rocket?
Take a look at the Loc Warlock. I am considering something very close to that with a 4 grain 75 mm L reload.
I have been looking at threads on the Gizmo XL and see margins of .6 being ok. Having trouble understanding that too hence my original question.
I've heard that OROC has launched a beer keg to a serious altitude, but I don't remember exactly how high.
Rocket was called Beer Daddy if I remember correctly. [EDIT] Yup... Beer Daddy it was. [/EDIT]
Apparently that last one had 175lb's of beer, and a donut of unknown weight, on board. It reached an altitude of 6100'.
Now that's what I call alcohol abuse! :lol:
Hi Len B and thanks. I am familiar with the cone transition in Rocksim for short stubby rockets. I guess where I have my problem is understanding when said rocket is or not short and stubby. I am unaware of a formula to use for determining such. Something like the Warlock (or a Door Knob) is what I have in mind and I want to fly an L2200 in it. The Warlock, without the Rocksim transition needs about 11 pounds of weight.
As Bob said, rockets with a large base drag have a different CP than expected and require less nose weight than you might think. Somewhere in the Apogee Components newsletters there is an article that describes a way to more accurately compute the CP using Rocksim. I have a Minie Magg and I added 900 grams of nose weight to account for a longish 38mm motor. It flew well but was definitely too heavy. The first flight saw the nose cone attachment point ripped off. (I was new) That 1Kg nose cone came ripping down and pounded through an inch of ice. It wasn't damaged. I changed the attachment to something considerably more robust and I've flown it on a J motor since.
I too have a LOC Warlock and I intend to build it with a 98mm motor mount so I can fly it on coffee can K's. I'll have to dig up that Apogee article. The solution involves adding a conical shape to the base of the rocket pointing towards the nose. I just cannot remember how to determine the length of the sim cone.
I'm trying to remember the huge rocket from Balls 23 which had some ridiculous quantity of water in the nose cone for ballast that was released at apogee.
