I'm a wee bit flustered here. I've been handloading rifle and pistol cartridges for 18 or so years.
Just started using QuickLOAD, so to be thorough, I thought I'd check the bulk density of some of my propellants, esp. since the temperature at the range in the People's Republik of Southern Kalifornia is over 100 degrees F this week.
I have a bunch of surplus WC852F, which is comparable to H380 &/or BLC-2 (depending on the lot). Here is how I determined the density:
Get a sized, primed case. Put it on Dillon scale. Zero it.
Fill to the top with distilled water, trim the water level with a steel ruler so that the meniscus is perfect. Weigh it. Weight in grams equivalent to water volume in CCs.
Empty case of water. Blow out with compressed air. Blow in some brake cleaner (kiss that primer good bye!), blow it out again for 30 seconds or so. Let it sit a spell.
Put it back on Dillon scale. Zero it.
Take scale pan, fill half way with propellant. Put powder funnel atop case. Pour in propellant. Rap case sharply on side with metal object about 50 times. Remove funnel, let a tiny heap of propellant stay atop cartridge (easier than trying to cut it level with a steel ruler, and, it makes not much difference in any event.)
Divide. Third grade stuff.
For the WC852F, I get
which, compared to a couple of identical references (0.0691), is about 2% heavy; no biggie.
Now, try the same thing with a lot of H4895 I've had for a while (not much longer than the WC852F, mind you!)
compared to the same references (0.0728 gram/cc) this is about +15% heavy. Sheesh.
Repeat for a lot of Varget, same approx. age.
compared to same references, (0.0731 grams/cc), about +15.5%
I did the same trick with AA2200DP, compared it to AA2230, it was right on the spot.
All of this propellant has been stored in the same place, in original 1 lb containers, in a Southern Kalifornia garage that gets a little warm sometimes, but the weather is generally not to hot or cold with moderate humidity. Besides, the bottles are all nearly full and sealed.
What the What is going on here? I have repeated the Hodgdon tests enough times to (hope I know that...) I am not totally nuts.
Some adult supervision, if you please?
