Big Dan from RMSS fame is running it for RMSS people. They have ammo, a lot of ammo. Yes, they have 9mm, 40 and .223 by the pound. They also have bulk boxes of various ammo. Some firearms and accessories. Nice place to stop on your way to or from Great Guns or Pawnee. They also have steel and other targets available. I stopped after the Freedom Shoot. Handy location.
As to the loose bulk, they get the barrel stuff in huge boxes and put it into the barrels. Barrel or huge box, ammo is the same, it's not reloaded ammo, it's first run stuff.
