Powder zombies are pretty normal and really don't affect anything. You can increase the start pressure with the FCD but I don't think that is the best way to go about it. Use the FCD to guarantee that the bullet don't pull from recoil. Warm up the load to get better combustion, or switch to a faster powder if you need low velocity. E.g. Hodgdon Clays will burn cleaner than Hodgdon Universal for a given velocity.
