No it's bp. I found 1 year ago the correct formula for it but didn't know the pape anymore. It burns slow but with the small Nozzle and the Visco going half into the motor and burning fast the rocket motor has power.
They are pressed with very high pressures so your motor was weaker than the bought one.
Rocket propellants didn't need to burn fast, if the rocket motor is optimized for it.
I have tried much sorts of propellants but the RP from VK2ZAY's page is powerful enough and made a nice tail.

I would say you don't need the dextrin. I have rammed my bp rockets dry
I also added a bit Al to the bp for nice tail.
Try to make smaller ID rockets and get them to fly.

I have made a small solid rocket.
Fuel was KNSO. 16mm iD and 65mm long, 30g header.

and the vid

The rocket was very high....
On the vid you can see the D1 effect and about 1 sec later you can hear the bang.

I used the Epoxyd resin from the 2 component glue.
I can't write a guide cause I'm in the conclusion year....

@ BPBR: Why buy?? Build your own rocket....
Construct with Space CAD to see if the rocket would fly
and if it's stabil.

My favorite fuels for modelrockets(because they have much power) are:
1: 64% KNO3
26% Epoxid
5%-S
5%-Al
and
2: 2:1 KNO3/Sorbit(diabeticer sugar)
melt the Sorbit(slow and not too hot) and than add the KNO3 and stirr.
Allow it to cool or pour it into the tubes. You can add up to 5% Fe2O3 or
ascorbic acid for more power

The second one is cheap and if the propellant charge is big and long
enough a high about 300 ft and more!! are possible to reach.

EDIT: PS: I shot an rocket over 450ft high in the sky
