Any suggestions from someone who has any actual experience?  Thanks!

One word: machine gun.

Ok, I've never hunted hogs from a helicopter, but I have shot machine guns from helicopters. Get yourself a machine gun and thank me later.

Rumors of killing 300 in 3 hours have been greatly exaggerated..... I’m sure there is somebody, somewhere that has. But most fly around between properties, managing their resources, just like every other business does.  There was an outfit that flew a big place down the road from us. Twice a month.  Guys ax meats claimed 100+ every time they went out.  You’d see a lot of buzzards if it was accurate.  We never saw many buzzards...

Not enough large tracts of land here. The GD claims to kill about 100 but I think that's how many they run onto the neighbors. I think it would be fun but only for a short while. But hey if you got the money why not you only live once!

I went out near Bonham, TX. We killed 8 over 4 hours. It was fun but expensive. We would have certainly killed more if we had seen more but that was about all we rustled out of the woods.

Heligunner! Everyday and twice on Sunday.

Especially if you weigh more than a buck-eighty

Did a day with them a few years ago between my FIL, BIL, and I and it was a blast. Even got my then very small children up for a quick joy ride and they still talk about it. I really need to get the dollars together to do that again.
