Probably just fine for 300 yard work, but not great for anything further.

I sincerely doubt that it actually throws charges equal to the accuracy of the scale because stick powders tend to bunch up and fall in groups, then you need to fix it manually anyway.

If you’re a long range shooter, be careful about getting hot for this new shiny and consider getting a better more accurate and stable balance like a Vibra milligram scale in combination with an old school powder thrower to get close. Then just adjust manually for the last few kernels. Your final loads will be within less than one kernel of Varget.

One of the points to keep an eye on is voltage fluctuations and other things like phone signals affecting the accuracy of the scale. Most are just not as accurate in reality as claimed, so if you want two decimal place accuracy, then you need a 3 decimal place scale.
