For saving space, I use a trick my friend GRAY from Florida showed me.....get a traveling tooth paste holder...that has a good secure lid.....you can alter that some what to make a tight fit....add foam to the top, and press some into the long end....add just enough not to put pressure on the caps, and mark which end is the capsule end.....
This is great for carrying the 140's in a backpack, or my set-up which is a water proof thermal 18 can beer cooler....completely water proof to set on the ground ( Coventry was a great tes FOB) holds dap1,ad2k,v-2 and various batteries and supplies
