Where did all the H1000 go? Is it the current unobtainable powder like H4350 was not long ago? I was hoping to grab a pound of it to test in a 300 RUM while placing a primer order but it seems that no one has any. I haven't purchased any reloading supplies in a year or so and didn't realize it was hard to find. I would like to at least compare it to Retumbo in my rifle before I look for an 8lb jug of Retumbo.
