They dont make the 1-38 twist anymore either but it shoots real bullets and maxihunters and 230and 250 XTP in sabots real good[50 cal]and in 54cal mine shoots widner 300gr soft points into a ragged hole @ 100 with 140 gr RS, the old System One uses musket caps and dont get crudring or even very dirty cleanest shooting inline I have ever had. Lymans one of the best low priced ones,the Omega Z5 is the only one that can be found in that price range sometimes thats better. Lee
