Have not used these in over 4 years. Too lazy to load, factory ammo spoil this old guy. 650 set up on both; station #1 is a 21st Century universal expanding die with melonited mandrel. I sent my fired brass to commercial processing. The last 15Ks were primed, I make sure the necks provide close to the same neck tension. Thus, the reason the expanding mandrels.
You notice, the dual powder measure? I think that helped (if you think it helps, it helps..lol) in the consistency of the powder charge to charge. I split the total between the two. Not exactly in half, just roughed it, one stayed fix. The Dillon powder measure adjusts the volume by changing the hole opening, instead of depth of the hole. So, the two smaller opening as you swipe across the powder tends to give less variation.
When I shot a lot, I loaded my long line ammo on that 650. The other ran the short line.
