The 3.0-3.2 grain load of Bullseye should be perfectly fine in the pre-1918 S&W .32-20 Hand Ejector, as it is a standard pressure load, 770-830 fps. Some data sources go higher, up to 3.4 grains, 900 fps, but I don't recommend it in the older guns. You have to be careful not to shoot Ken Water's loads intended for the later heat-treated models in it, because you will loosen up and shake the gun apart.
