powder drop

  1. powder drop weight changes

    Reloading
    I assume the drop weight of powder can be affected by humidity (as well as static) but does it vary as much 1 grain? I was getting 16.6 g of Clays powder (Canadian) a few months ago and now it's only about 15.6 with the same bushing. I live in the Seattle area so the humidity is much lower right...
