The 338 isn't real finicky.

H or I 4350
H or I 4831 (remember, data for H and I is not interchangeable)
RL-19
RL-22
RL-25
I7828
AA 3100

Those are the powders I've tried and they all worked fine.
MRP, H414 and a bunch of others work well too. I'd say whatever makes a 280 or 270 sing works and has data for those powders. It likes a little slower fuel than the 06.
At present all I use is RL-19, 22 and 25.
