Might check these folks out. More often than not, Cody has what I'm looking for and he ships as well.
Checking his inventory, he doesn't show any H1000 right now but, you can call or email him and find out when he expects some.
With local dealers here charging mid-to upper-$30's for powder, he's a breath of fresh air price-wise.
Not to mention, he's the FFL for the local Friends of NRA group!
