I did!!! I went on the hunt for ammo yesterday as well, but didn't find anything acceptable (for tube fed) in the box stores. I gave all my .44 mag ammo away to @dennishoddy a while back in the Pay It Forward thread. I didn't think to check pawn shops though, and ended up buying 100 rounds from SGAmmo last night. I wish good luck to @Honey Badger finding some locally. They might have better success since they aren't limited to options for a tube fed gun like I am.
