shaman,

shot placement and penetration, not power, is the key to success. Anything with a TTSX works well. A .260 with a 100 gr TTSX, .308 with 130 TTSX, or .308 with 175 SMK are what I use most often and all work well.

The .243 with an 80 TTSX has worked well enough, but is the only Barnes bullet that has failed to exit.

The .44 Mag tends not to penetrate consistently on the larger pigs from personal experience.

What are your other options?

If you can reliably make the shot, aim for the base of ear, otherwise go for the base of the neck down 1/3 to 1/2 from the top of the back.
