Is anyone else running an RCBS Chargemaster 1500 combo? I'm interested to know how long it takes your machine to "settle" and start throwing the charge you've set. I was trying to push out a box of ammo using H1000, and for the first 10 charges I got overages 60% of the time. By the time I got up to 20 charges the failure fate had decreased to 50% before seeming to get it right fairly reliably. Still, it's a bit of a pain to have to dispense a couple dozen charges only to have to dump them because they were a few tenths of a grain over.

I even tried setting it low and use the trickle button to work my way up, but "trickle" evidently means "dispense anywhere from one half to one full grain of powder".
