I feel bad for guy who tweeted as someone from East Texas. Main reasons I want to go into hunting is to the keep wild boar population in check, or at least slow their growth.
I'm from Central texas, own 50 acres in the hill country and own several ar-15's. This guy is delusional, no one is shooting 30-50 hogs on their property. I only read the first few paragraphs but so far the conversation is ridiculous.
The sharpest shooters can get a few as they scatter, they are damn smart and very capable.
They fly in helicopters and can shoot that many in a day. Its usually very large areas (thousands of acres) with a surrounding game fence. Since the hogs have no natural predators they have to be removed somehow and this is one common route. Vastly different scenario then a small 50 acre place.
That is not a good idea. Innocent people will die when forgotten mines go off in a decade, and full auto weaponry is probably overkill. I can't imagine your aim is going to get any better when you're firing in full auto, unless you're far closer than you want to be.
Plus there are far easier solutions. Poisoned corn does about the same thing as mines, but with less risk (assuming you put up signs) and cost. Both are probably still bad ideas, though, because of the effect on other wildlife.
