You can get just about anything you need at either of these two places...Do you have a good source for powder and primers? Local as in Tulsa? I have bought a lot from a place in McAlester call All Pawn great selection low prices and I travel there for business about once a month.

You can usually save a little at the Tulsa gun shows... there's usually one every 4-5 weeks or so.
