Lots of sites such as mats just use meal and pulverone for lift but now I can press my meal into cakes and sieve it into different sizes will this produce better results?

You do not need or want hard grains for this purpose, so pressing would not be necessary. The grains need to crush when you ram them, or you'll end up with a salute. Therefore rocket propellant is granulated like pulverone, but with little or no dextrin.

My rocket is ID 20 mm, nozzel 7 mm, total length is 100 mm and core is 80 mm
Is there any different using Granulated BP in term of lauching height, speed and carring load?

200 meters is very high for a black powder rocket.

The sound of the rocket is scary, I mean loud....
I used 100 mesh to seive my BP by using a vibrator.
For the high is not an accurate measurement. I tested the rocket near a 30 story building and watch the rocket from 400 meter distance. It goes more than twice of the building hight. That's how I came out with 200 meter.
