Of course, that's if you don't mind paying ~$7.10/rd
Yep, if you happen to own a Barret or something else in .50BMG, you can run up to Cabela's and pick up several boxes of ammo for it!
Granted, it's ~$71.00/box of 10, but at least they've got it!
Now, where did I hide that credit card application, or maybe I'll take out a second mortgage...
Still gotta find someplace with a Barret to sell, too...
