I don't have any problem sharing my "below maximum" loads with others, but would never do it on an open forum. My max, and beyond, recipes are between me and the Almighty. But I've been reloading for over 50 years and over that time learned quite well what to look for in terms of pressure signs. I've heard the published loads referred to as "lawyer loads", meaning they are limited due to liability concerns. But know what you're doing before even going close to a max load. On the powder storage topic, I think a greater concern beyond the 75 kg max storage from this act, is what does your insurance policy say. My guess is that little or no storage is allowed. Need to look at my policy since I probably have stored powder in the 25 kg range.
