Was just at the Grapevine location and they had a better stock than I've seen in a while.
Brass: (I'm sure I'm not remembering all of it)
Handgun: .45, .40, 38, 380, 454, 500
Rifle: .243, 22-250, 7mm mag, .338.
Powders: about 10 different ones (call and ask 'em)
Just passing this along. Not a GREAT selection maybe, but it's getting better.
