We slaughter the wild hogs here in Texas and on a good night can kill 30-40 in a night. For eating we just cut the hind quarters off the 100-150 pounders. This is helicopter hunting. For eradication not fun.
They cook up really well on the grill. Gas or charcoal.
I imagine younger ones taste a lot better.
When I was a kid we ate a lot of wild game mostly squirrel. The young ones were much better in every way.
