That's the way I use mine! I thought I had an original idea, then I come here and see a lot of other people do it,too.
I installed a white LED under the turret so I can see the charge. I even ground away the corner of what woud hold a left front post if there WAS a left front post. I can really see down into the case.
With the powder measure in station number 1 I don't see a way to use the chain. I use the powder measure with the spring from my turret press.
And yes, the case feeder works wonderfully.
