Humidity, dank affect reloading?

    I'm wondering whether Salem's dank Winters, humid Summers affect reloading. I haven't figured a way to set up my gear in the house so I will probably set up in the garage which has an ambiance that tracks the conditions outside.

    Right now my tentative plan is to set up in the garage and have a propane heater for the colder days. I do not know whether the heater helps with dankness.

    Store primers/powder inside or at least in a sealed container. You need ventilation with the propane heat or you could end up with a greenhouse affect. Also when done reloading wipe down dies and press with a light oil to avoid rust.

    Humidity control is a bit of a problem in a residential application during the winter months. In the summer, not so much because you can run an AC unit to bring the RH under control without freezing your rear off.

    Propane heat will humidify the air.

    I reload in a detached, unheated garage. When it's cold I run an electric space heater to bring up the temp.

    Haven't had any problems to-date.

    I store my powders in their original containers in that space and always empty out my powder hopper at the end of the session. Since primers aren't in sealed containers I store them in the house.

    Yea, what they all said. I would just recommend storing the primers inside since you need to be careful of what type of sealed containers you place them in. Lots of primers, in a small, sealed, metal container is called a bomb.

    I reload in my garage. Store all my primers and powder inside though. Never had any problem with heat or humidity. I use a Little Buddy heater when it gets too cold.

    What I have found is heat and humidity can have a dramatic effect on group size. The load that shoots great in the summer needs adjustment in order to shoot great in the middle of winter.
