Unfortunately everything seems to be either in short supply generally or hit and miss. As far as I know Federal isn't having manufacturing issues, they just can supply everyone. The U.S. market always gets preference because they're just bigger.
Buddy uses Federal ammo and he was having trouble finding his flavour last deer season too (may have been Power Shock). He ended up using something different and luckily in the end his 80 yards shot made it moot if he was off by 2 MOA or sumptin.
I'm zeroed with Sako ammo for my .308 and when I finally found some 180s last year before deer season, I bought a couple boxes extra. While it does nothing to easy the shortages for the masses, small scale hoarding when you find stuff is your friend.
