The footprints you use are for parts with much larger leads. Reduce the drill size and pad size and you should be ok. (Check the datasheet of your device and see what the maximum size of the lead is specified to be. Add a bit to that for solder and the tolerance of your drill sizes and you should arrive at something closer fitting your part.
