Given that 4350 is such a popular burn rate powder, it seems like the Accurate brand of 4350 is not very popular. I've seen it in stock for multiple days now on Powder Valley, Natchez, Brownell's, Hodgdon web sites. I have never used it. Burn rate charts and load data manuals suggest it is the slowest of the 4350 powders (maybe Shooter's World is a tad slower).

Are there temperature stability issues? QC problems?

What say you??
