Saw an ammo bag a while back and then didn't  save it to my favorites.  I know stupid move...
It is a small square kit bag/ tool bag design meant for carrying loose ammo.  It had a fabric collar that cinched at the top.  
Does anyone know this bag? It seems to be a pretty unique design.  I would post a pic but...
My search fu is weak tonight......
I have begun to think about that bag, wanting to dump a couple of .22 bulk packs into one.
If you have other options that would be great as well.

EDIT
Thanks to the 13 who looked..... here is what I was describing

I have 5 of these, I love 'em.

why is this a better alternative than just keeping ammo in boxes?

My first glance guess is that the ammo is already unpack-aged and ready to go.  Boxes/Plastic take up unneeded room.

Those are nice but $34 seems a little pricey.
