I seem to recall having seen a chart at one point but can't find it.

I'm upscaling a Big Bertha and have to decide on a stuffer tube......

Thanks.
 
if memory serves...Estes motor ejection charge equivalents are 18mm approx. 0.5g and 24mm roughly 0.7g

if that were the case...you would never deploy the laundry in an executioner :). according to my 'calibrated' mk1 eyeball AT 24mm and 29mm charge wells are the same size.

With a bit of googling I think we're both mostly right. From what I can tell:
Estes 18mm 0.5
Estes D 0.7
Estes E 1ish
AT 24 0.5, maybe less- I thought I heard something about them being underfilled a while ago?
AT 29 0.7
