So, I think I'm going to get a humidity controlled cabinet (typically used for camera equipment) to store my opened containers of powder, The reason for this is that I've been loading my 300 PRC from an opened jug for the last few trips out, and my go-to load has been running a little hot resulting in sub-par SDs. For my latest loads, I decided to open a new 1 pounder to see how things changed. The result was that I lost 20+ fps and my SDs dropped back in line (~6 fps).
Humidity has been pretty low here in CA (roughly 35%), and I think my open jug has been impacted. We go through pretty serious seasonal swings (many days of 90% plus in winter to <15% in summer), and it is clear to me that it is impacting my loads enough to cause me problems. So I'm thinking that the solution is controlling humidity for my open containers. I don't need a big cabinet, and there are a number under $300.

In my next house, I'll install a room-sized humidity controller in my reloading room.
