The one I would stay away from is the Pact BBK II electronic scale. That' s the small one. I' ve got one and I have very little (if any) confidence in it. Here' s one example why:

First, they say to let it warm up about 20 or 30 minutes before using it, so I always did. I say " did" because I don' t use it any more. Anyway, I was loading up some 7.65 Arg. rounds (20 to be exact) one day and weighing each charge. I wanted 47 grains of IMR 4350 in each case. After I finished loading each case I was curious, so I recalibrated and rezeroed the scale then reweighed the charges in random cases. Some weighed 47grs. while some weighed almost 48.5grs. I had to dump every one and reweigh everything using my Redding Master beam scale that I have absolute faith in.

That was not an isolated incident. I have weighed brass with it as well and gone back to recheck the first ones weighed and they would weigh a full grain or so different the second time around.

From what I understand, the more expensive Pact is a much better scale. Right now I weigh all my charges on the Redding beam scale, but I am considering buying another electronic to weigh bullets and brass.
