As far as I know, Dillon presses are not fussy with other mfg dies. I am using RCBS .308 dies on my 550b alongside my slew of Dillon .45, 9mm and .30-06 dies. As long as each calibre is on its own press quick-change adapter so the powder doesn’t get muddled and settings stay fixed, you are gold.I got a used Dillon XL650, missing a few parts though.
Can I use my RCBS 9mm dies? Or would Dillon be better?
