Thanks for the quick response, Youngeyes!
I was trying to answer the question for myself first. The best I could find was this: http://www.brianenos.com/pages/dillon/cal.conv.chart.html#550cross. But I don't see 6.8 SPC listed here anywhere.
Follow up questions:
1. Does the info in this link (http://www.brianenos.com/pages/dillon/cal.conv.chart.html#550cross) apply for the 650?
2. Is there another link or reference that has additional calibers such as 6.8 SPC?
3. The above linked page explains the a) shell plate, powder funnel and c) 3 locator buttons. Is there another reference that covers the other items listed in Youngeyes post above, i.e. the d) "station 1 locator #2," e) "feeder adapter orange," f) "feeder arm red," and g) "feeder body medium"?
Thanks!
