How may the temperature of the reloading room effect reloading?

That's a good point. Something I didn't really think about. I store my powder in my garage. It's dry but it does get cold. Then I bring my powder into my home to measure it at least when it is cold. That could be introducing moisture as you say. Might be wise to store my powder inside as well. The powder manufactures just say to store the powder in a cool and dry environment. I'll have to give this some more thought.

Wouldn't that also affect loaded ammo? It it was cold and you brought it into a warm truck or tent--‐ is it really an issue?

I know some muzzleloader guys that leave their loaded rifles outside the whole time when hunting , saying if they bring it into a warm area it will sweat and the moisture might affect the powder.....anyone tested these theories to see if they hold water?

I know the whole "hitting a rain droplet" thing is pretty much debunked by people that have actually proved it ( like J E) anyone actually test the whole "moisture/sweating " thing at all?

Look up "coefficient of thermal expansion" (CTE). It's very small differences when you're dealing with bullets and brass sized objects. In order to affect small objects you need extreme freezing temps or high temperatures to safely press some item into or onto. Like a bearing onto a shaft, a pin into a hole.

Here's what's important…make your reloading room comfortable enough for you to stay there working on projects away from your wife for hours. That's it, that's all you need to consider.

I guess it would depend on how much air is in the case and how much moisture is in it. I bring my sealed powder in the house the day before and let it slowly warm. Just my way

what do you all think is a good humidity?
my basement stays about 45%

Tell your kids you are taking over their bedroom. Reload in the house. Problem solved.

"My" ideal operational temp is ~55F. I do not sweat much more than most, but humidity and static electricity are the two things I like to control.

ADDED: My main reloading area doubles as wine cellar.

Or a good Bourbon cellar, salute

Kids are gone... It's the wife that won't let me have one of the old bedrooms!

For the most part don't over think things.

The only thing to give consideration towards is letting your scales/ powder dispensers time to do is warm up, most have a timer before they will be operational and thats due to the gel in the mechanism needs to warm for calibrating weight.

The brass, powder and primers don't care what temperature it is when sizing and reloading.
With all that said some of my stuff has to be accurate to meet today's demands when the clock-timer is ticking away and I have to hit a plate at 3500 to 4200 yards away so believe me. I am one of those annal reloaders.

With that said I do monitor and have had a humidor in my slow burning 20n29 powder for years because when shooting the 2 to 2.25 mile crap it just saves a lot of load adjusting and keeps things in the zone.

All the other stuff I don't worry about powder Humidity just the slower burning stuff in which has a higher degree of having to be perfect in the equation and distance.

My reloading area is in an unfinished part of the basement without HVAC. I monitor humidity and run a dehumidifier pretty much 24/7. Temps range from 75 in the summer to 60 in the winter at the extremes inside this area. I try to maintain relative humidity below 52.
I'm in the southeast so humidity is extreme in the summer. My dehumidifier is over 20 years old and still going strong.

Thank God I do not have that problem. The wife suggested using one of the basement bedrooms as the main reloading area. It's just the wife and me now, too.

Good idea, but not so in Louisiana.

No basements down here, you'd need a sump pump to keep the seepage from ground water pressure out!
Yep... will seep through the smallest voids of 6" solid concrete walls.
