Round Rock, TX, is just north of Austin. They just opened this past Tuesday, Aug. 27 - I first heard about their new store from radio ads last week, and they've been running TV commercials too.
I've been a GM customer since they had their original mail order business in Wilmot, WI . . . .it must be over 40 years ago now; as a young'un, my Dad and I even drove up there from Chicago a couple of times when they started over the counter sales of reloading components. They began opening retail stores some years later, and eventually took over the Burger Bros. chain in the Minneapolis-St. Paul area where I was working at the time. Went through some re-orgs as I recall, but have been off my radar since I moved to TX in the '90s.
They took over the building that used to be Sportsman's Warehouse. It's about what you'd expect from Gander Mountain, but the whole back of the store is their gun shop, with plenty of rifles, pistols, shotguns, EBR's, safes, a couple of .50s, even some used guns and milsurps. Prices seemed rather high - they had about 5 dozen Mosin-Nagants for $180 each, a Chiappa Rhino (1st I've seen) for almost a grand. Also looked at a scaled down Browning 1911 in .22 LR . . . nice little gun, but at nearly $600, I figured it wouldn't do anything better than the .22s I've got now.
Centerfire ammo was AVAILABLE . . . at a price. Examples: 1000 round cases of Federal AR223 for ~$600, 350 round boxes of CCI Blazer Brass 9mm for ~$120, as well as bulk packs of .380, .40, and .45 ACP. The only common round they DIDN'T have was .22lr, other than birdshot.
