How important is it to do reloading in a climate-controlled environment? I know its preferable, but is it a necessity?
For me, it's very important for several reasons:
1. Reloader comfort/fatigue, focus/concentration and socializing with family. I used to reload on my garage bench standing up whether it was hot or cold. Over the years, I have found that my focus and concentration was less than optimal when the weather was too hot/cold and I was not comfortable/fatigued. And if I was reloading a lot, I was away from the family quite a bit.
Although I still have my garage bench, I since built a 2'x3' portable castered reloading bench (picture below) that allows me to reload anywhere in the house (livingroom, reloading room, patio, etc.). The small size allows the bench to go into the reloading room from the narrow hallway and gets pushed into the walk-in closet of the reloading room when not in use. Although the bench is non-traditional in that it is not heavy (about 80 lbs empty) and not mounted to the wall, C-H 205 single stage press mounted on one end can resize thicker walled military .308 cases without issues even with the bench empty (I keep bullets on the bottom shelf so I would guess the total weight of the "working" bench to be around 200-300+ lbs loaded).
Now, I reload in air conditioned/heated comfort sitting in a cushy office chair while actively socializing with my family. I still do dirty case sorting/tumbling in the garage but resize/case prepping indoors. I do the final reloading early weekend mornings while everyone is sleeping and I can focus/concentrate without distractions.
2. If you are using digital scales, most have specified operating temperature ranges. The small MidwayUSA FA DS750 scale I have used for years (now discontinued and replaced by new model with swing cover) is accurate to .2 gr (verified by Ohaus 10-10) but comes with 15C - 35C (59F - 95F) operating temperature range. Some reloaders that complained about the inconsistency of the scale, when asked, admitted to using outside of the specified temperature range.
I now do all my weighing indoors whether using beam scale or digital scale with the door to the reloading room closed and A/C vent turned off. The reloading room/house stays 65F - 70F year round.
