I don't have Quickload, but it seems very similar in case capacity to the 300 Hawk cartridge (basically a necked down 9.3x62 which has 77gr water capacity as a parent cartridge). The 300 Hawk is advertised to get 2801 fps from a 22" barrel using IMR 4350 under a 200 gr bullet. I don't have the charge weights for the Hawk cartridges, but the load data for that is cheaper than quickload.
Sorry this isn't load data, just another place to start looking for answers.
Machine guns are awesome until you have to carry one.
