Thread: Reloading Manual Preferred Powder

Something I have wondered about.

When reading a manual for the caliber and given bullet weight is it assumed that the powder that is at the top of the list for the given weight is the preferred one
Or does it make no difference EG

308 Norma In the ADi manual for 200gr Nosler partition
ADi 2209 then
2213sC, finishing with
2217.
And there is no Retumbo/2225

Does this mean the preferred power in the rifle and barrel length stated is 2209 the least preferred is 2217 and 2225 shouldn't be used at all in the opinion of the bloke who put together the manual?
Or perhaps its simply that it was done alphabetically ?
