I hunt hogs in Oklahoma at least twice a year (it's kind of like heroin now!).
I would LOVE to have private land to hunt on, but if I can't find it, I go to Shiloh Ranch near Ada, OK. I would be extremely interested in a Texas hunt on someone's property!
At Shiloh Ranch, the owners are really great people. They typically cater to bow hunters, but are ok with firearms. I've used a Super Redhawk 44 to take anywhere from 160lb through a big old 230lb boar. The hunt is "relatively" cheap, and they have a choice of rustic air conditioned cabins or a house with three bedrooms to stay in. Every time I've been there, all of us have been successful. Hunting with a firearm is only from an elevated stand or designated ground blind - there is no spot and stalk with a firearm, but it's still a ton of fun. Lots and lots of hogs - hardest part is choosing which one to shoot (and controlling your breath and heart rate when doing so!!).
Shiloh Ranch is at
http://155.212.11.42/, or search for them on Facebook. The web site has not been updated in a long time, and they book hunts fast. As of last week, the next available date was May. Best bet is to call them. Matt and Cheryl Napper are the owners, and do all the work.
I'm going back on April 28-30. I have a group of three, but they normally want to book five hunters, so two spots are open. We will be staying at the house. I will have myself (handgun), my son (Ruger 77/44), and my buddy (handgun) those three days. Most shots are late evening in low(er) light, dense woods, and less than 25 yards. I know we don't know each other, but I'd rather hunt with guys from this forum than those strange guys with sticks and strings.... -just kidding, I like bow hunters too...
By the way, I am in no way affiliated with Shiloh Ranch. A friend asked me to go who had been going there for years, and I have never regretted it. The owners are REAL southern folks, and expect the same sort of respect and behavior that all hunters should have. I have seen people that were disrespectful to them or the ranch be asked to leave or not come back. They are picky about who they have on their ranch and can and should be. If you are not a polite, respectful lady or gentleman, you would NOT have a good time hunting there. What I'm saying, is that if you are a smart-a$$, or a "know it all", or take a stupid or bad shot, or are not smart enough to practice and be proficient before you go, don't expect to be treated very well when they have to chase down YOUR wounded boar in the dark! They are real outdoors people, and Matt and Cheryl have trophies from all over the country/world that would make us all jealous!
I don't normally tell a lot of people about this place, for fear of not getting hunts booked, but it is a great place. Inexpensive, comfortable, and tons of fun. They also offer some ram hunting and other exotics, but the hogs are just too much fun for me!
