My understanding is slightly different than what is represented above. As far as I know, all lead shot has some antimony or some other hardening agent in it. Chilled shot has essentially become a marketing term with no real meaning. It doesn't indicate how much antimony is in the lead. The term Magnum shot is usually indicative of a higher level of antimony, but higher than what, since they don't give comparative numbers. Tom Roster(sp) I believe, did an article comparing differently marked lead shot that one can buy fior reloading. The inconsistency between what the shot is marketed as and the actual comparative hardness was striking.
