Part of the problem with Texas......
is that when Texas joined the Union in 1845, they kept title to all their public lands, unlike other western states where the public land was turned over to the U.S. government. So no BLM land in Texas.
Texas either gave away (for compensation for military service in various wars) or sold almost all of its public lands.
There are WMA's (Wildlife Management Areas) controlled by the state which are available to hunters (deer, turkey, small game), but even they require an additional license fee, and they can be pretty crowded in the fall. Firearms are restricted from some of them (Bowhunting only), and NO target shooting is allowed on any of them.
There are two Federal Grasslands areas in North Central Texas (Caddo National Grasslands) which are available for hunting with no special permit required, but once again, they get crowded. And NO target shooting allowed there either.
There's also some public land around the man made reservoirs around the state. This is land controlled by The Army Corps of Engineers. Permits are required there too (most are free) and NO target shooting allowed.
Hunting in Texas is becoming a rich man's sport. Most hunting leases will cost you around 1000.00 to 2000.00 a year per hunter. I grew up here and still love Texas, but the days of asking permission to hunt a farmer's or rancher's property for free are pretty much done.
And pay-to-shoot ranges are just about the only answer for target shooters and plinkers. Most of them are fairly restrictive. Most won't allow rapid fire, some won't allow FMJ rifle ammo, and some won't allow you to shoot your own reloads.
Dang.......I'm depressed.
