They do not list a min or max load. Only one charge.

Unique is 5.5 grs=1111 fps

231 is 5.0 grs=996 fps

out of a 6" SW barrel.

Only use 38 brass not 357, use only lead shot, #8 and #9 recommended.

Seat them slowly to avoid breaking them, crimp lightly, use a flat seater plug (wad cutter) if you have one.
