Powder choice?

[MtPockets]

I'm trying to decide on a powder for 260 Hammer Hunters in .338 RUM with a 30" barrel.
Seems like generally speaking with the longer barrel, a slower powder is recommended, right? Is that also true with the Hammers?

I have the following on hand:
H4831
H4895
H1000
RL26
Ramshot Magnum
US869

Thoughts? What should I expect with the different powders?

Hammers have less engraving pressure, they typically recommend using a faster powder. Look for published load data from your powder choice with the next closest lighter weight bullet and start there.
