I'm a beginner reloader and several months ago I asked what powder meters the most consistently with the Lee auto disc powder measure.
HP-38 was mentioned by MANY people.
Today I actually tested it out.
Using a digital scale that has 0.02gn resolution, I threw 10 charges with HP-38 and disc 0.53 cc
The charge measured 5.38gn
I then tared the case and powder combined so I could see only the differences for the next 9 charges.
I got 0.00 for the next nine!
No tapping, nothing special, just pulled the handle each time. Hopper half full.
And yes I confirmed this wasn't something dumb, the scale still measures different values and everything makes sense.
This is incredible!!!
So my question is, what powder for 223 loads would meter as consistently? This would be awesome for rifle!!
I'm guessing this powder meters so well because its such thin flakes, making it much less likely to have different volumes depending on minute shakes or vibrations.
The powder I am currently using for 223 is reloader 7 and its been treating me well for what I'm doing. My goal is to buy expensive new brass (Lapua etc..) and combined with 69gn sierra matchkings make as accurate ammo as possible.
Sierras data for the 69gn is below..of those powders which would meter as well as HP-38?
