I love my lee auto drum, it’s always within 0.1gr of the set weight, but that’s not the best thing on my bench.
I would have to say that there are 2 things that have greatly helped me,
The first is a simple insert for my cordless drill that has 8-32 female threads to accept case prep tools. I chuck up the adapter and a small primer reamer and can go through no small amount of 5.56 brass in short order.
The second is my APS strip priming tool and strip loader. Since switching to that from the Lee XR, I haven’t mangled a single primer or installed any backward. I’m actually thinking about getting the bench mounted version to see if it’s even better than the hand tool.
