1 - I use CC's, specifically I use a Lee PPM, or Lee dippers. I was going to use powder measure once, but that unit didn't have volume units, just hashes.
I HAVE BOTH THE PPM AND THE DIPPERS...I WILL TRY BOTH AND SEE WHERE I END UP..
2 - Honestly, only 3 for an 8 # Jug. I haven't bought a 1# in a long time.
ALL 8LB JUGS HERE AS WELL
3 - No. That number always moves. Unless it worked out that that many CC's weighed that much, in your testing. The number is how many grains/unit of volume, in my example that unit is CC's.
I WILL USE CCs AS WELL....SO IN MY CASE 45.8G X 0.07916667=3.62583349 CCs SO ILL ROUND THIS OFF TO 3.70CCs OR AM I WAY OFF HERE?
4 - Good question, and this is the tricky one. How do you store your powder? There is a great article in the newest Norma manual, testing/discussing how much moisture change affects burning rate; even from a SEALED container! So how long you store powder, how much the temp and humidity varies, all plays to it. Most don't know that the S.E. corner of Washington is a desert, 3" total precipitation last year! I personally test mine every 4 months. I'm not sure what is "Right", but it works for me.
I STORE MY POWDER IN MY SAFE...I HAVE AN 4LB BAG OF KINDRY IN MY SAFE AND LIVE IN NORTHERN NEVADA SO ITS DRY HERE...
5 - There is some very good info in Modern Reloading on this, if you want to know more about volume. But here are some suggestions for you.
I HAVE THIS BOOK AND WILL TAKE A LOOK...
-Remember this is for extruded powder only.
THIS IS ALL I USE...
-How ever you decide to do your volume test, do it Consistently. If when weighing, if 0.1gr is important; then carry that particularity over to the volume side.
- Don't confuse the two methods. Don't try and take your favorite weight load, and make it directly translate to volume; they are different.
GOTCHA...
