RE: Powder Measuring Accuracy?
Here's what I do in case it's of any assistance to you. I use a Lee Perfect powder measure to throw charges about1/2 grain less than what I want. The Lee is an inexpensive measure and looks and feels like a piece of crap, but it's surprisingly accurate. I then weigh the charge on my Redding beam scale and trickle up to the weight I want. I'm not a big volume reloader, so this works well for me. I've used a PACT BBK electronic scale also, but found it to be too unreliable. What kind of scale do you have BTW?
