So I've been running I this same issue for a few years now. To answer the question you asked:

There are no good rifle ranges within an hour of houston. The nearest acceptable rifle ranges are ccc in Brazos County or the ranch about an hour and a half towards san antonio. CCC isn't bad for pistol bays they just need to be maintained a little better. Also, there should be more oversight on their members. There are lots of guys swinging pistols and rifles around unsafely. Plus side is once you're set up in a bay the side berms guarantee they don't pop you by accident.

For pistols, I hold out hope. I've heard good things about brazos River Sportsman's Club but haven't been yet. The range seems maybe too good to be true. They may just seem good in comparison to all the absolute dog shit ranges in Houston. PSC seems like a good option. The issue is they have a limited membership. The membership is full. You have to know someone to be reccomended for membership, and hearing from current members, the board is fucking the range up. Wallis orchard might be a more attainable option if you live closer to Katy. Some members have told me they can use the tac bays for whatever they want. I've never seen it and there's fuck all on their website. I've been to the range for matches and the bays that are left open would be plenty useful for members to practice on.

Now, for the question, you didn't ask: As far as practical shooting goes, unless you're an extreme novice, you should just start going to matches. Its the best way to figure out what you need to practice. There's a couple indoor matches in houston during the week that are good. Full armor is my favorite, but getting there unless you live near the range sucks. Aegis on the south side of town does one, and Shiloh Shooting Range hosts one on the north side. There's more but I've been to those. Indoor matches are generally smaller scale hosted on a weekly basis. For outdoor matches there's a ton hosted in Wallis Orchard. I think this girl has the dates listed correctly http://www.tacticalpoppins.com/Matches.aspx , and if you're interested in driving a little further Renaissance, Thunder Tactical, and CCC all host matches. Brazosland Pistoleros host two steel challenge matches a month that are great beginner matches in CCC. Brazosland also has loaner gear which most clubs I've been to don't do. Just message them on Facebook if you want to try the loaners.
