    First thing I would do is to make sure that the powder is still in safe useable condition. Winchester first started making the stuff in the early 60's. Unless you know where it's been all these years, and how it's been stored it could be a dicey proposition. Specially as it's rated as a very fast burning, high pressure pistol powder. If the chemical characteristics has changed over the years due to improper storage, it might be best to get rid of the stuff.

    My old Winchester data shows that it's rated as a fast burning pistol powder. With very low charge weights similar to the modern fast burning powders.
    AA 2, Bullseye, 231, HP 38, etc.etc.

    Use the sniff test on it.
    If it smells like a solvent, it's OK if not; chuck it.
    Hodgedon reprocessed some WW1 powder so it can last a long time.

    Radar,

    Powder should be stored in a cool, DRY place with as uniform a temperature as possible.

    When powder starts to break down, you will see a rust color. Pour a small amount onto a white paper plate & check it in good light. If no rust color or rust colored dust is noticible & there is NO caking or clumps from moisture, you are good to go!

    When powder deteriorates it gets weaker, never more powerful.

    I have a copy of Speer #7 reloading manual with load info. for 230P in 38 wadcutter & 45 target loads.

    The Speer #7 manual was published in 1966 & copies are up for auction on verious sites from time to time. Check the auction side for 'Speer 7 manual' & you will find one before long.

    Jim

    edit; Any powder that shows signs of deterioration or dampness should NOT be used. The danger is in the increased possibility of "squib" (very weak) loads that can cause a barrel blockage, or in "hang fire" (delayed ignition) loads.
