I need to buy some powder, and I'm intending to do it up big and buy a 25 pound lot. And I'm overthinking it and not getting anywhere.
As one reference, I've used Goex 3F main and 4F prime in every caliber rifle & smoothbore I've owned.
.40/.45/.50/.54/.58/.62cal rifles and .54/.56/.62cal smoothbores
Barrel lengths include 27", 28", 32", 38", 42"
Best case prices I ever found was buying directly from a Goex Distributor.
I mixed each case to always include 1 can of 4F.
Then mix cans of 3F (and/or 2F) as you see fit
Goex web site lists the distributor names/addresses/contact info.
If you're within reasonable driving distance of a Goex Distributor, you can avoid shipping/handling/HazMat fees all together.
Further, at a Goex Distributor counter you can buy it in a 25lb bulk bag inside a sturdy Goex box for an even lower price per pound...single granulation of course...but it’s so inexpensive if you mainly wanted 3F, get it bulk then just add a few cans of 2F/4F to your over the counter purchase.
