I'm running off an 8lb jug I bought in Alaska 2yrs ago. I haven't seen more than a single 1lb container here in Missouri for the last year. This is what lead me to RL26, RL17, H4831sc and so on. I just can't rely on H4350 enough to bank a load on it.
I was down to about half a pound when cabelas got some in stock a while back. I picked up two eight pound jugs. Probably should have bought more but figured that would get me buy for a couple years and give another guy a chance at some. Good luck on your h4350 search.
Ramshot Hunter is one that everyone overlooks. Its a ball powder in the 4350 burn range and works fantastic in the 6.5 Creedmoor. Others that work great:
RL16, RL17, IMR 4451, H4831sc
there are more but I know those powders all work very well in the 6.5 creedmoor
