After using a Pact for years I finally gave up. Electrics are good for weighing brass and bullets but the drifting became so annonying I went back to the beam scale for powder charges.
Much happier reloader now

I should think any powder dispenser that does it all automatically is going to introduce errors. AC current is 60 cycles. If it falls to 57, you'll get a different charge. Same for if it goes up to 62. A digital that measures what you trickle into it will vary, too, but I think when you trickle up, you'll quit as soon as the display hits the target. That's what I do. As soon as I see my target weight, I quit trickling. I like to think this gives me a weight at the bottom of that 1/10-grain increment...

I don't understand all this "drifting" y'all are talking about. The powder tube on my 1200 is threaded just like a powder trickler and when it is churning out a charge, it rotates just like a powder trickler until it gets close to the desired weight. Then it stops and precedes to turn the tube in little bumps until the desired weight is reached. Sometimes, a few extra grains will fall out or the scale will be right at the cusp of changing so that the next bump brings it over and the read out will be .1 over. If I were to check it on a Ohaus 10/10, I would find that it was 25.3 rather than 25.2 like it should be. In other words, the 1200 is telling me how much powder is in the pan. It's just not the correct amount. I dump it back in the hopper and call for another load. I've never had a situation where the weight shown on the read-out was not what was in the pan.
As I've said, my 1200 handles some powders better than others but then my powder measure handles some powders better than others. I'd much rather measure course stick powder in the 1200 than use the measure and trickle up any day.

This is the best of both worlds, beam scale with electronically controlled single kernal trickler. It is faster and more accurate then anything out there.
