Get an Uncle Mike's which holds 10 cartridges for wearing on your belt, or one for the stock of your rifle. That plus a magazine full could support a small war! If you really feel the need for more, throw another box in your backpack.

I am looking for an ammo pouch
-velcro closure
-holds 20 rds of centerfire ammo
-carried on your belt

I purchased one last year but cannot find now
