Here is South West Mississippi (a lof feral hogs here), our best way is either with live traps or dogs.... Hogs are extremely wary, typically nocturnal here and much harder to still/stand hunt than deer. I'd suggest bait.
I can also recommend Varget and RL-15. I've had better success with Varget in the 30-06, but RL-15 did work well, just not quite as clean in my application.
I favor the 140 grain Nosler Solid Base for the 7mm-08. I used in for years in my 280 Remington before it was discontinued. Unfortunately, the 280 Remington and other rifles went up in smoke with a home fire.
Now that I'm shooting a 7mm-08 and the Nosler Solid Base is available again, I think...
