Friends and fellow followers of the Holy Black;
Bill says polishing to a 1.02 G/CC to 1.08 G/CC LOADING Density is generally accepted on Sporting Powder.
IndianJoe my mind rang a bell, when I realized this was what you were speaking of, a couple months back, that you didn't care as much for puck density as loading density? Now I understand what you were saying.
Thanks ! I just didnt communicate that well enough
And final screening for dust removal yielded further positive results.
Yes! I am a screen freak - believe the industrial/commercial process leaves room for improvement on that score
The addition of Graphite seems to add more of a pouring and grain isolating advantage, in storage.
I have been shooting ungraphited powder since the late 1990's so have got used to the down side - but on the positive we have one less source of inert material in the powder. Graphite slows ignition, adds to fouling - only a little bit but little bits add up as we go along.
It will not give much additional protection to moisture
That was one of the touted reasons for it in early days and I never found it to be true.
and actually will hide an underlying moisture problem below the polished outer layer of grain structure from long term storage.
It 'moderates' ignition throughout the burn process, which can help stabilize accuracy. A potential negative of Graphite is added fixed carbon content, which will add a certain amount to dryer fouling characteristics.
I had already been through the graphite vs ungraphite with bulk Goex so was never tempted to add it to homebrew
Do use it on all my lead ball for muzzleloaders - stops the crud from developing in storage.
Good job I think we are doin better with our own stuff than we realise.
There's pretty much the extent of my notes. As
VettePilot says, "your mileage may vary".
