Get a bigger chamber!
With a chamber of about 450ml and a .75" diameter barrel, I can shoot a projectile twice as heavy (44g) at 230m/s using only a 10x mix.
Your cannon will work brilliantly for projectiles about 15g and less but a larger chamber will probably be needed to get the most out of such high mixes (20x +) shooting reasonbly 'heavy' projectiles.
