If only shooting 100 yards, I go to Quail Creek. If longer Fossil Pointe or ETTS.
Do you have a 100 yard indoor range? Mission Ridge (Plano - https://www.missionridgerange.com/) may not be close, but they have one. Frisco Gun Club I think has a 100 yard indoor range. Not sure if that's closer than Mission Ridge though. I bet there's something indoor that is close is the point.
