I've used the RCBS and the Hornady tray, but both of them, the smooth half will "bounce" some of the primers as I'm filling the tube, causing them to flip anvil up.
Are there any flip trays out there that don't have that bounce?
Not to push the Dillon koolaid, but I have a Dillon Primer flip tray and I don't have any problem with the primers changing orientation during pickup. I have never used anything else so I can't speak with any diverse experience.
