Hagen,
You can find reloading supplies in the greater Killeen area at the following locations: JT Sports in Copperas Cove (next to the Kettle Restuarant) and Guns Galore. I've bought bullets, primers, and powder at both locations and seem to recall both locations having presses, dies and so forth. There are a couple of gun/sporting goods stores in Lampasas that carry reloading supplies and equipment: The Bore House and Nocked and Locked.
There is a Sportsman's Warehouse in Fort Worth, not far from Cheaper Than Dirt on the north side off of I35W. There are Cabelas in Fort Worth and in Buda. All have reloading supplies and equipment.
Have fun, hope the SIL gets something out of your instruction.
