What presses and dies are you using and general equipment recommendations.

If you set up a 550B or XL650 correctly that is not true. The case indexes off of the face of the ram, not the shell plate...

I stand corrected...

The Dillon 650 does have 'calibre' specific' locator pins (Part #11) which will line the case up with the generic top plate die axes. There's no other reason why they would have different pins for different calibres. The Lee Loadmaster does not however. 650 Parts list here;

My pins are for 9mm and I see they are stamped '3').
