I used to shoot quite a few of these. Had to reload...factory cost waaay too much. I haven't run across my old data for the .32 yet. I do remember I was shooting 85 gr Horn JHP, Fed brass, CCI 500's and some 2400. The darn little thing was really accurate and pleasant to shoot. I never tried cast bullets in it, but that would seem like the best choice for all-around shooting.
