Two members on this site make quality components for this caiber.
Dave Wilson (FC60) on this site makes dies.
Rich Daniels (Barreltester) on this site makes shellplates and adjustable powder bars.
I have one of the bars that works and is of excellant quality.
Most of the other parts are required for small primers are somewhat more readily available. For tubes and some primer parts, send a note to Bruce WIlliams (RBWillNJ) on this site.
