Brute,
You are correct in that you need to hit them from all angles.
The point I was trying to make is that one could hire out a heli and still come up short in a contest.
It's why they call it HUNTING.
Sorry, yes, you never know. Just like that only getting 9 hogs.
But if you come down to a heavily populated are like here. Its money in the bank. Like I said, they get 100 to 300 hogs (kind of depending on how big the ranch is, smallest maybe 5K biggest 100K+) regurlarly on the ranches we hunt and surrounding ranches, that is free range, no high fences. That is running during the day from say 10am to 4pm. Can't remember for sure, but for a day like that it is around $3K-$5K. With TDHA giving out over $2K this past year... its not to far off of an idea.
They use to have guys that would go with goosekneck trailers and pick them up then they would haul them to a big pit. Now they just leave them. Typically these guy use .223s around here. They will do the same for coyotes.
