Why not sand in a small plastic baggie? Leave it unzipped and let it spill out at ejection.

Sand is a far too cheap and plentiful material to have any business being used for rocketry.

Sounds like a plan to me.

Anyway, I'm in the process of scratch building a 3" OD x 63" long rocket and it looks like I may need about 3-4 ounces nose weight to obain one caliber on the static CP. So I'm planning on the sandbag trick. I'll probably use a small paper parts bag as it will disintegrate soon after the first rain.

Or, maybe I could use dog scat? What do you think, GH?

How about lead shot mixed with epoxy ?

Dog poop belongs in flaming bags used for pranks.
I leave my ridiculous ideers/comments in the free-for-all section where they belong.
For True rocketry questions, I try to provide legitimate viable answers.

Can dried dog $hit smell any worse than black powder residue?

In all seriousness, what I'm looking for is additional mass in order to shift the center of mass forward. By filling the nose cone with epoxy and lead shot, have I not created a solid mass capable of inficting significant damage to any object that it might impact should something go wrong? Additionally, I wouldn't be able to remove this mass should I use a lighter motor.

Why is lead, zinc or other dense material the only option? It seems to me that sand, dry clay or any other natural material either in the nose cone or in a bag would be a viable option. And cheap too!
