ArchAngelCD,
Vit is "available" here, but the price makes ordering it a bargain. Over $40/pound (n320) locally. $24/# at P.V.
As always, order in bulk if possible; but in this case it really makes little difference by the time you add gas money and tax.
n320 is the #1 powder for minor PF 9X19. Clean with light loads, soft recoil, not temp or position sensitive, meters excellently in anything, can't double charge, "cool" burning, no muzzle flash, single base powder. The actual cost/rd is actually slightly less than 1 cent more than 231. What 231 will make at 4.3grs, n320 makes at 4.1grs. Close to the same "quantity" of powder needed from Titegroup for the same speed.
I don't own stock in the company, but it is an amazing powder. Sure wish it was made in America.
