I had the brass factory running yesterday. This is 9mm range brass that I've picked up over the years. It wasn't super dirty, just average stuff you find laying around at the range.
I knocked the cycle time down to 1 hour, and it looks great. So here's what I've come up with for a formula.
1) Fairly clean brass = 1 hour
2) Moderately dirty brass = 2 hours
3) Really nasty stuff that you want pristine = 2 hours, water change, 1 hour. (may be able to knock the first stage down to 1 hour, I'll have to try that sometime)
The thing I really like about the wet cleaning is that it gets the insides of the cases clean. I don't use a progressive press. I load 50 at a time, and after I do my powder charge step, I take my reloading block under a light and inspect the powder level in all the cases. The shiny insides makes that part much easier.
The other positive aspect is no dust like you get with the vibrating bowls. Dealing with the water is a bit of a hassle at first, but once you get a system down, it works really well.
