Do Openrocket motor lengths include the length of the casing or is it just the length of the grains? I'm looking at the Aerotech K750 and the Openrocket length is 10.51", while the total length of the RMS 75-1280 casing including closures seems to be 10.259". I'm not sure if the missing length is due to the nozzle sticking out past the aft closure?
