Default Ejection charge

I'm building a rear ejection rocket, 24mm MMT in a BT-80 airframe. The motor tube is 300mm long and the airframe tube is 310mm long. The front of the motor tube butts against a bulkhead. The front centering ring is 30mm from the front of the motor tube.
I need to find out if the ejection charges on LPR BP motors are all the same. During ejection testing do I need to use 24mm motors or can I use far cheaper A8-3s?
