Taking the Pain Out of Loading Extruded Powders

New Tools from RCBS Almost Make Loading Fun

 

<- Previous page

 

My reloading table in Minnesota is a simple brown folding office table, but since space is at a premium in Arizona, I ordered a reloading table from Cabela’s.  Assembling the table was an exercise in frustration, as the directions were terrible.  However, it does have a solid wood laminated top and plenty of drawers to hold small tools, dies, etc.  The red color of the drawers is a bit much for my tastes, but the unit is functional.  Bottom line on this purchase: $350 is a lot of money to spend on a table that takes a whole day to set up.  My guess is you could do better by contracting with a woodworker or building your own.

 

After assembling the table, I unpacked the box of reloading tools.  The RCBS Rockchucker press is an “O” design.  My mouth watered when I stroked the operating lever up and down – the mechanical leverage of this press puts the old Pacific “C” press to shame.  It also seemed as if the tolerance of the ram was tighter.  Next up was the real gem in this package – the automatic powder measure and scale.  I use a lot of extruded powders but have a hard time using a measure – it is just not as accurate as using a laboratory quality scale.

 

The RCBS electronic powder dispenser, called the PowderMaster, works in conjunction with a digital scale RCBS designates the PowderPro.  No assembly is required, and both units use household current transformed to 9 and 12 volts AC.  I was quite happy to see that there are no batteries required, but a little disappointed that the units do not use the same power supply.  To eliminate confusion, I plug both transformers into an extension cord, and plug or unplug the extension cord into the wall socket, eliminating any confusion.

 

I have long used powder measures, tricklers, and scales, but the combination fielded by RCBS provides the accuracy of a scale without the tedium.  Notice I didn’t say speed, because while the unit is much faster than the using a measure and trickling on a standard style scale, is not as fast as a measure.  Essentially, the dispenser dumps a coarse amount of powder into the scale, then trickles in at a slow speed until the scale is brought to the desired weight – without any other intervention or activity required from the user.  You use a numeric keypad to punch in the desired powder charge into the dispenser.  The dispenser then receives data from the scale to distribute powder into the scale pan.  A huge charge (75 grains) takes about 50 seconds; smaller charges take less. 

 

But make no mistake - this is not as fast as a powder measure.  You can speed things up by using a mechanical (human powered) powder measure and setting up the electronic dispenser to act as powder trickler.  However, I don’t see time as a critical factor.  One minute per load (including dumping the charge pan into a prepared case) is not that much time.  And there is nothing from preventing you from performing other activities while the electronic powder metering is going on.  For example, if you are charging cases for a .220 Swift, then you can resize .223 Remington cases, prep them, or perform other tasks such as listening to a football game on TV.  Like any other scale, vibration or other movement can interfere with its operation.  Therefore, it is probably a good idea to set the scale and dispenser on a separate table.  I cannot envision using the dispenser and scale on ball powders, but then, I cannot imagine using anything but this setup in the future when I do use extruded powders.  Loading 50 cases with extruded powder is no longer something to dread.
