One of the time consuming parts of reloading on Dillon presses is the manually filling of primer tubes. I do have the Dillon Auto Primer filler, but it can sometime be a pain in the a.... If you don't pay attention a small percentage of primers go in the wrong way.
Today I ordered a DAA Primer-Pro Collator from Double Alpha. As of now the collator works with only small primers.
I'll give you a report when I have it in my hands.
