You gotta get the smaller ones. The bigger ones I’ve heard are just BAAAD even if you like pork. But I have heard that the ones less than 100 lbs are good eatin’.
I’ve also heard that it depends on what the critters are eating — I would suppose if the pigs are eatin a bunch of swamp crap, than they would be likely to taste like crap, but if they are eating grass and open range greenery then they are good. I intend to put the theory to the test at some point...
Nice when you can test a theory with a Weatherby .270 and a New Braunfels smoker as lab tools.
In my experience it completely depends on what they are eating.
My husband killed a 400 lb russian boar that was eating in a peanut patch. We couldn’t tell the difference between it and store-bought pork. We even served it to company.
Another time he killed 3 little ones that a rancher had trapped in a pen. They were so foul tasting we had to throw it all out.
