I have been on a 4 or 5 month search for H4350, without any luck. Does anyone have any definitive news on when/if we might see some of this powder available? I did find some IMR 4451, which was supposed to be exact replacement (or so I was told), and now it is non-existent. I have heard all kinds of local speculation about being some coming available, but nothing for sure. Anybody know anything about where it can be found, and when?
