Grain question with regardes to BATFE

With regards to the 62.5g limit, is that per grain or is that the
total weight of propellant in the rocket?
Cheers,
Matt

Some agencies call it Propelling Charge Mass. Others call it net explosive weight.
So both.

note that the Cesaroni Pro-38 133G69-12A is also the only G RMS that would be unaffected by NPRM 968. This is due to the fact that the single grain G69 is encased in a module, and so cannot be combined with additional grains to assemble a motor containing more than 62.5 g APCP [without deconstruction]. OTOH, AT grains are capable of such reassembly.
