.410 Buckshot loads

I was wondering how hard to cast 00 Buck pellets for my .410 buckshot loads ? I usually cast bullets & buckshot soft, but I understand that the 00 pellets in .410 buckshot loads can deform under acceleration, and was thinking of doing a batch of hard-cast 00, with antimony and quenching, and using a water trap to check deformation, compared to soft-cast 00 loads. Thoughts ? Thanks, George
