I have a Lee 1 oz mold. I actually chatted with John Lee and he said the 1 oz was a little better than the 7/8 oz. I have loaded up many and they seem to work well once you find the right WAD and powder combination for your gun. Some wads have thicker or thinner petals that will produce different results in different guns. I finally got the right loading for my Ithaca Deerslayer II and they shoot extremely well. I would say what the load is, but it is a litttle over recommendations, so I guess it is a secret...I don't need the liability.
