Well, lets see there's heat, humidity, mosquitos,... did i mention humidity?
Only two ranges listed in the phone book, both on the South side of town.
The indoor range is called The Sharpshooter (361 980-1190). It's an ok facility located in the knee of a strip mall. I've noticed that ventilation leaves a bit to be desired since if you get a couple of guns going at the same time the range starts getting a bit smoky. 15yrd pistol and 25yrd rifle ranges IIRC, and 8 or so positions for shooters I've never counted. The pistol range has more than the rifle. This probably won't be a problem as I've never seen the place busy. The times that I've been there I've had the place all to myself. BOTH ranges. Probably means they won't be there much longer, but OTOH they've been there about a decade. Their Yellow pages ad claims IDPA matches and Pin Matches (there?!!) which I knew nothing about until I read the ad. I'll have to check into this.
Actually the matches I was aware of occurred at this other range on sunday mornings (actually all day but they started around 8) It's a few miles down the road from the Sharpshooter. Just go down Airline until it tee's into Yorktown. Go Left about a mile and be looking for a gravel road Right (South) Go down that road about a mile and after a curve left you'll see a pasture gate on your right. Go through that gate and up the "hill" and you'll see a house on the right. Thats the office of Starry Shooting Range (361 992-1935)
It's a rather scruffy looking place but it seems to generate more business than the Sharpshooter. You're pretty much on your own here unless the "range officer" decides to wander down towards the range to check if anyones bleeding. It has 25yrd pistol and 100yrd rifle. Downhill. The pistol range isn't that pronounced but the rifle has a definite grade to it. This is because the location of the range is right on the upper portions of the Cayo Del Oso (Oso Bay) and the rifle and pistol range fire towards the water. Ten years ago the berms were low enough you could see the water over them but he's raised the berms since then. You'll notice quite a bit of shot up trash on the ground of the pistol range. This is frowned upon but happens anyway.
This "facility" had the pistol match stages. If you stand at the office facing South You'll see two low corrugated steel structures straight ahead. These are the rifle and pistol ranges. Rifle left and pistol right. Further right is the "skeet" range. Just sort of an open field with a well used launcher at the corner of the pistol range berm.
To the left of the rifle range you'll see a road going down towards the water. This is the pistol match range. 8 or 10 stages, I can't recall exactly, firing East which is fun in the morning.
There's also the Corpus Christi Pistol and Rifle club snobs
who have a facility out on Old Brownsville Rd and FM 763 (361 852-1212 P.O. Box 7117 78467) While I know where their range is, I've never been there nor have I talked to any members. The snob comment is just my take on other people's reactions when I have mentioned that organization in the past.
After that it's try to find a quiet out of the way place which is both not quite cool and surprisingly hard to do. The large ranches patrol and guard their territory and prosecute for trespass. Just about everywhere you could go is private property and posted. If it's the limited public access areas (rivers, drainage, etc.) then there a a large amount of people around.
Most of the time it seems that a deer lease is about the only other option and some of those stipulate no firing unless trying to take game. Others don't give a rip as long as no one gets hurt.
OTOH I live in a rental here on the Nueces River just outside the city limits and the amount of gunfire on the weekends is just amazing. I guess some people just step out their back door and let fly. A lot of it is shotguns after dove but some handguns are heard. You can tell since they like to empty their mags ASAP. This particular property isn't suited to that as there is a house closer to the river on both sides. But those houses have people that shoot every now and then.
