I have my press set up in a ouside shop, but all of my components are keep inside.
Will humidity outside affect reloading if so what percentage.

My real issue if my brass, powder and [primers are in a warm house, will it hurt them to loadin a cold shop enviroment.  What i mean is if metal is warm then introduced to cold will it sweat, or is it the other way around or will it matter either way.  Inside temp around 70 going to outside shop temp of 30-40 degrees.   Any concerns i need to be aware of.


thanks

Shouldn't cause you any problems.

Other than the "sweating", no problems other than a cold reloader.

Warm air can carry more moisture than cold air. A cold item brought into a warm space may cause moisture to condense on the item. An item brought from warm to cold would have to be very moist to cause problems.

An extreme case. When I lived in Alaska I made some handloads in 44 mag with some powder that had been setting in a powder measure in an apartment. We used a humidifier in the apartment. We took his new Marlin 44 mag carbine out in 55 degree below temperatures. The factory ammo worked fine. My reloads made a small pop. The primer fired but it just drove the bullet and a frozen plug of powder into the chamber.
