I believe Pacific was the first with a fixed charge rotor, with the same basic design marketed by Bair and Hornady(?) Eventually RCBS got into the act with their highly successful Little Dandy and its selection of 28 sizes of rotors. Lyman made a brief, moderately successful sortie into the game with their Accu-Measure, notable for its 15 available rotors, with about 10 having two chambers, allowing for about 25 charges. I’m still using the Pacific, the Little Dandy and the Accu-Measure for certain jobs because I’ve never found anything I like better.
