I just bought a 1 LB BP core burner set from Caleb been doing some research on different rocket formulas and been noticing that a lot only have 5% sulfur in them just wondering why this is and if anyone would like to share their tried and true formulas your welcome to PM me if you dont want to share your formulas in public before I get burnt up on here I do know this hobby is about experimenting and dialing in until you find what works but some of us have less time than others to experiment I would love to spend more time in the shop just not possible at this time

If it where me I would leave out the clay nozzle. And just ram hot BP in it 75/15/10. And use 1% to2% water. Screened in the fuel.
You can fire them as fast as you can make them. At least that would get you started.
Nozzles motors are pretty reliable and fast and easy to make. Good luck.

60 - 30 - 10: Tried and true. Start there with a hand mix. Use finely powdered KNO3. It's hard to mess up.
