I bought the Lee .690 round ball mould and made some myself. I loaded them to trap load velocities and used them to determine point of impact for a few of my shotguns. They are so small they seem to shoot better with some choke. I think with a cylinder tube they rattle down the barrel, but with some choke they exit closer to the center line of the bore. Any ways, that's just my theory.
They shoot well, and would probably be good deer killers within buckshot ranges, but I don't hunt with them.
