Hi folks! What are you useing to break individual powder kernals to achieve .001 grain load accuracy? And why? Bench shooters in competition "throw" their charges and are satisfied with tenth of a grain accuracy as more can be gained by doping conditions than splitting a split hair. I have used a chargmaster for years and like it. It is precise enough that temperature variations and air flow in the room affect it. See ya!
I have a Denver Instruments digital lab scale that has been on continually for about 20 years. It’s been a wonderfully accurate and dependable tool. This scale, and many others, will not allow you to trickle in a few grains of propellant at a time, as it messes with the electronic zero maintenance feature. On the extremely rare occasion that I need a single reasonably perfect charge, I use an old Redding beam scale and a magnifying glass in conjunction with an RCBS powder trickler. I have a set of calibrated test weights and both scales have performed flawlessly.
So, what’s wrong with the XT 1500? Mike
Accuracy is about consistency. Volume consistency is more accurate than weight consistency. Buy yourself a Niel Jones powder measure and never look back. I have fired many many thousands of rounds always seeking the last bit of accuracy and the Jones measure is the key,

I use an AND FX120i(magnetic restoration scale), very happy with it so far and it was a good deal(400 cad), they're more $ in the US for some reason.
The volume measure is the trick, but you need the weight to set it and check it. I've never seen reload data expressed in units of "niel Jones volume measure drop" ;-)
Of course you haven't. You have to calibrate the measure to the powder. You drop a charge and weigh it then advance the micrometer and weigh the charge. Then you know that one click equals X weight of that powder. Say that you drop a charge of H4895 and it weighs 30 grains. If one click advance gives you 30.1 grains then 9 more clicks will give 31 grains.The volume measure is the trick, but you need the weight to set it and check it. I've never seen reload data expressed in units of "niel Jones volume measure drop" ;-)
