Agree, no need to carry two pounds of powder. That is why I usually carry three or four pounds plus a half pound of 4Fg.
Here shown only 2 lbs.
We often shot several calibers and I carried 200-300 balls for each. And, don't forget I had tools, including a vice in there. At most ranges I was the 'fix-it' guy and helped many a shooter. The box closed measures 19" wide X 11" deep X 13" high. I don't even want to know what it weighs.
I've been hauling it for 30 years but that may have to stop since my shoulders went bad on me.
There is an irrefutable rule about these things. The bigger the box you get the more 'stuff' you will need to fill it.
I do need to scale back.
But, it has been fun.
