I'm toying with the idea of buying a Dillon 550 press. I haven't completly decided on the Dillon, but I do want a progressive press.

My reloading room will be out in my workshop which is a large 'garden shed' type structure. Humidity can be a BIG problem, but I have several airtight 20mm ammo cans, with dessicant packs, for storing ammo and and other moisture sensitive items. The press will be permanently mounted, and when not in use will be coverd in plastic with a dessicant pack inside the plastic.

I shoot 400-1000 rounds a month in mostly .40 cal, but also shoot 9 mm and .45 cal.
Does anyone have any thoughts, opinions or recommendations especially as they relate to high humidity.

Thanks!

I think that most of the stuff related to reloading would prefer to be in a climate controled environment. Humidity will take a toll over time.

I have had the handtools that I use everyday on the job start to rust even while I was using them. I head for the oil can to keep side cutters, pliers and such working for one hand operation.

I also prefer to assemble ammunition in the winter when humidity is low. Or when the A/C is on in the summer. The bullet will keep that moisture trapped inside the case. I don't see how that could be a "good thing" for ammo that is to be stored long term?

I used to live in Vancouver, WA. My set up was in a non-controlled environment similar to what you are describing, I could not keep up with the rust and I was using it a lot.

It always saddens me to hear about someone's reloading equipment afflicted by rust due to a humid atmosphere. When you stop to consider that hundreds of dollars are often invested in this equipment and avoiding such a situation is easily dealt with by simply moving the equipment into a controlled climate makes it all the more preventable. Move your reloading bench and new Dillon reloader into the house. Regardless if you plan to plastic wrap it with dessicant when not reloading, you will still have to expose your reloader to the elements when you reload in the shed. Once rust gets started it is difficult to stop so give this some thought.

Thanks for all advice, I'm currently looking into other options that doesn't include a shed setup.

Don't overlook vapor barrier products. They can keep bare metal protected when humidity is difficult to control. It is a single-use item, eventually wears out and must be replaced.
An air conditioner can make a good dehumidifier, but electricity ain't cheap. I'd be thinking about coating the concrete floor is you have one, or otherwise trying to seal things up.
