# Powder Measure Redux Part Four: Trickling in...

### Great guns at unbeatable prices!

In our previous experiment we learned that even the best, most expensive powder measures suck at dispensing stick powders such as Varget. On the other hand, Varget has a number of amazing characteristics such as temperature independence and a burning profile that is particularly suitable for high power which make it indispensable component for long range shooters.

So how do we dispense it accurately?

The method that a lot of reloaders use is to throw a little bit less than the intended load, and then trickle the rest of the powder in using a powder trickler, directly into the scale pan.

What kind of accuracy does this method yield? Since you are normally trickling it into a scale with the best resolution, you wouldn't know (beyond the resolution of that scale), but with my super-accurate microbalance scale I could answer this question!

I did 15 measurements where I first dropped an underweight charge using a powder measure, and then trickled it to be as accurate as I could on RCBS balance scale.

As you can see, standard deviation is roughly 0.027 (the first number is standard deviation of a sample; the second is an estimate of the standard deviation of the technique itself - what would the standard deviation of an infinite series of measurements be.

This means is that there is a 99.8% probability that the drop will be within 0.075 grain from an average - a pretty good accuracy indeed!
