OP, I am holding you responsible for this!
I just ordered one of these:

Actually, both OP and (FRAUD ALERT) are responsible: OP for starting this thread and (FRAUD ALERT) because I found an unexpected balance on my account that went towards the trickler.
There are a bunch of videos on YouTube about this thing.
After watching those, I think this will help for the very small charges I use for my Swiss 1881 Ordnance and 38 S&W loads. This thing should be able to trickle those out entirely.
For larger cartridges, I'll drop the bulk with a powder measure or a scoop and use this to trickle up.
Will be interesting to see how loads from this compare to loads from the Lee Auto Drum.
I just cannot resist an interesting gadget.
