questions:
* how long does it take to drop something like 45 grains of 4350 into a +/- window of 1.5 tenths grain or .3 grain total window? How about the same with something like 2015BR or 3031 but say 30 grains?
* You spoke of drift, is this common? Or a rare thing?
* How easy is it to clean verses the older one?

Gary,
For starters, I don't doubt that others may have better or worse experiences with the same product. These are electronic devices and aren't necessarily made to the highest standards. Balance beams are pretty simple and trustworthy.
I just timed one 50g sample of h4831sc that came out to ~18 seconds.
I've used it with Varget, RL22, H4350, and one or 2 others with similar results.
If I bump the table, it'll sometimes read a tenth or 2 over/under and it has an indicator to remind you that it's over or under. In which case, I thump the tube to drop another granule or grab a pinch from the pan and toss it back in the hopper.
Drift hasn't been a problem. But, I try to be mindful and keep an eye out.
If it's been sitting, stable, level, consistent temp, I don't notice much drift. By notice, I mean that I watch the reading when I remove the pan to fill a case and it should go to -142.3. On occasion, it'll be 1/10g over/under. If that happens, I weigh another charge and if it does it a second time, I recalibrate.
I usually get through a batch of 50 without recalibrating.
If I'm sorting bullets, I keep one as a control and check it every now and again.
If I'm loading competition ammo, I use the Chargemaster first, and then set the pan on the Sartorious which is suppossed to be precise to +/- .02 grains. You have to be a lot more anal with that one to stay within that kind of precision. But, it can be done. And, it may or may not help with your groups.
It's pretty easy to clean. My biggest challenge is the small size of my loading bench. I have to make room, slide it around to the edge, and then drain powder back in the bottle. But, I try to plan ahead so that I'm not switching powder constantly.
I also don't try bunches of powder/bullet combos. I find something that's known to be trustworthy e.g. 6br+107SMK+Varget, or 6.5x284+142SMK+h4831sc. If it won't shoot something like that, something's not right. ...although, I'll admit I may miss out a special load every now and then.
Thanks
Richard
