Some difference. It's a lot leaner than store bought and has a little more redish color. There will be a slightly different taste, but this varies from hog to hog and greatly depends on their diet. Hogs from the coastal regions of my state tend to taste more like the brackish marshes they inhabit (not pleasant). In the piedmont where I primarily hunt, they eat more soft mass and generally taste better (acorns, muscadines, persimmons, and food plots).

As a rule of thumb, the smaller the hog, the better the meat. My opinion- Any size sow is good eating. Small boars are good up to 250 lbs. If you can smell that sewage smell when field dressing a hog, just stop and bury it.
