Default Proper ratio of rocket fuel?

Hi I am making a homemade rocket for my next science fair. The only problem is I need enough thrust, and i do not know the proper ratios to make ammonium perchlorate. I have made it but the times before it seemed it was to powerfull and destroyed the chamber in which it was stored. Any help would be greatly appreciated.

My topic is: "What solid propelent will provide more thrust and prove more efficent, Ammonium perchlorate (NH4ClO4), or Potassium Nitrate (KNO3)" ?

-Thanks
