powder dispensing woes/solutions
Posted: Thu Apr 15, 2010 2:15 am
So in my foray into reloading, I've learned quite a deal of information along the way. I'm about to start into my 3rd and 4th Calibers - currently loading 9mm and .380 ACP, have dies and everything but bullets for .38spl and 9x18.
I have the Lee 50th Anniversary setup, which includes the Perfect Powder Measure and the Safety Scale. These work well under most circumstances, but I've found that Blue Dot is particularly troublesome for getting a consistent charge to run out of the measure. From my internet readings, this seems to be a characteristic of the powder, due to its bulk and shape. Disc dispensers seem to be worse with Blue Dot than what I have now. This gets frustrating due to the sheer amount of time I spend measuring and weighing every single charge, as I cannot be confident that it will throw consistently. I'd guess that 75% of loading time is spent on powder charging - most throws have to be adjusted to get the proper weight.
The other two powders I'm using (Bullseye and W231) run quite consistent through the measure. One thing that bothers me is that if I run a batch of Blue Dot loads, any subsequent loads (well, Bullseye has been the only one I've done this with so far) are inconsistent until I run about 50 throws through the measure. It's as if the Blue Dot is leeching all of the graphite built up in the measure from the other powders, and throwing everything out of whack until enough non-Blue Dot powder is put through the measure to coat it properly again. I find this quite irritating, and wonder if anyone else has run across this problem. I'm considering just buying a bunch of graphite powder and running it through the charger before and after any Blue Dot runs to fix this.
Now, I'm doing single stage, obviously. Given consistent throws, this wouldn't be an issue, and were I running a turret or progressive setup, I think this same problem would present itself. A digital scale would save some time on getting the weight right, but wouldn't resolve the issue of inconsistent throws that have to be adjusted. So, I'm looking at an admittedly expensive solution to this problem, a digital dispenser/scale that automates the throw/scale process to get quick and consistent charges:

This kit is made by PACT, and is identical to the RCBS ChargeMaster combo. This equipment has very good reviews, but at $250 retail, I can't seriously consider buying one just yet. I am ever so tempted, though. Perhaps in a few months.
I guess I have a couple of questions here:
Have any of you experienced this behavior with Blue Dot or other similar powders? If so, have you found any ways to get a more consistent charge?
Does anyone here have experience with the PACT/RCBS dispenser/scale combo? What has your experience been with it?
