    Ordering stuff to work up a new load in a 300 win mag and read in two different reloading books that RL22 or RX22 was good powder. One books list as RX22 and one book lists as RL22 but have identical velocities and pressure and load start and max. Any help would be appreciated. Thanks

    Lyman's Manual talks about that in their Powders Section, and notes that the Alliant Reloder powders are designated as 'Rx 15', 'Rx 19', 'Rx 22', etc.

    My Sierra book calls those powders 'RE-15', 'RE-19', etc

    Hornady & Nosler list them as 'RL-7', 'RL15', etc

    My Speer book spells them out: 'Reloder 22', 'Reloder-19', etc

    They all refer to the same powders: 'Rx 15 = 'RL-15' = 'RE-15' = 'Reloder 15'
    (Don't ask me why they do this)

    I believe they are the same powder. Somewhere in each reloading manual they should have
    a key to their abbreviations.

    Along with the previous abbreviations, it's also seen as" REL" 22, 19, 25 etc.
    All the same powder. I've read that Reloder 22 is identical to Norma MRP rifle powder???

    Yep, just a slightly different coating on the powder.

    Cool, thank everyone for the input. I did find an article of how the abbreviations are listed in different manuals differently and what they mean. Again Thanks to ALL
