1,250 lb is 567 kg. MTOW is 1317 kg according to Wiki. Assume a hopper that's half full, say 300 kg and a total weight around 1200 kg. Dropping that load will give you 1200/(1200-300) = 1,3 G instantaneously. If we're using MTOW and a full hopper, it goes up to 1,76 G. Not a problem on its own, but it all adds up.
