If you're going thermal, then go quiet. Get a can and go 300 BO shooting heavy bullets at subsonic velocity.
Where I'm at hogs run at the first shot and getting over 3-4 can be challenging. Running a can could let you get serious about helping the hog problem. And since you're going thermal, what's another $1000?
I've also killed a few with 55 gr NBT's and 77 gr SMK's in the puny 223 but at supersonic speeds, they seem to die good enough. If you don't want to go suppressed, then any caliber will work.
