Switching over to 284 Win from 6.5x284. Need a little advice on parts needed to switch the Redding die set for use with 284. My understanding is that I need a 284 sliding sleeve and seating stem. Are their any other parts required? It's a 6.5x284 Comp Die set. Also, what size bushings are recommended for neck sizing? I am planning to neck up Lapua 6.5 brass and use the 180gr. Berger VLD. Thanks in advance.
