Weight of powder dipped by volume vs. published min-max charge data

[FLSlim]

FWIW, dippers often scoop loads that are a little lighter than specified on the chart. This must be a "built-in" margin of safety by the mfg. The same is true for the Lee auto disks. You have to weigh the powder throws from volumetric measures to know what you are really dumping in the case. For general range use, I wouldn't worry about a powder trickler, just find the dipper that is nearest to the charge you want to use--just stay under max.....

If you dump a bunch of baseballs into a box you'll notice there's a lot of space left between the balls. Now shake the box and the balls tend to settle. Same concept applies with a dipper. What is happening here is that you increase the average density of the powder in the dipper by agitation. This results from the flakes/spheres/rods settling to increase the packing fraction.

Try tapping the dipper - the powder should settle leaving space for more.

Different powders will give different results depending on the particle's geometry.

I used to reload a long time ago and one reason I quit was I never could get a powder scale or a powder measure to give the same charge evey time. I still have primers and powder left over from the Clinton era. I would rather just trust factory loads and forget it.

LOL sell them to me at Clinton-era prices, fellow Palmetto-stater!

jebus!...

However, the weight of a level dipper of Power Pistol using a .5cc dipper is about 5.5gr

buy a powder drop... the lee is like 20$...
