Is there internal organization in them (i.e., loops)?
My biggest issue and one that @
TCinVA has mentioned seeing in classes before too, is that dump bags make it hard to index the shells properly when you go to grab them out for a reload. The number of times I've come out with two or three shells and at least one of them is flipped backwards is too high for me to really
want to use one of those unless I had no other choice. For carrying ammo you're going to put into belt holders or side-saddle or whatever they work better than a big box, but for fighting use, I'm a no, unless there isn't another good choice.
Edit:
Take the above mentioned ESSTAC cards, or Wilderness Cards from Vang Comp - slap them on a Ferro Concepts Mini-Chesty -

Bam - you got a micro-chest rig, where you can rip the cards off your chest and slap them on your gun OR feed from them off the chest rig.
