The M1845 is a 55% M reloadable composite motor from Aerotech.
This reload fits an RMS 98/5120 motor case.
Aerotech's Blue Thunder propellant produces a bright violet-blue flame with a minimum of exhaust smoke. These motors provide a higher level of thrust than White Lightning or Black Jack motors of the same total impulse.

This is totally wrong, The AT M1845NT goes in the 98/7680 Case, its a 3 Grain and is their New Blue Thunder propellant, and Total Impulse is 8,308 Ns
