That's a nice rig there. With hotter loads would it make a decent pig gun in the bush?
Vikram, I think it would. The parts of Texas I've seen wouldn't necessarily require such a short lightweight rifle as this, but in the eastern part such a light, short rifle would be an advantage.
Ballistics By The Inch will give you the calculations you might want to consider, when thinking about this:

The general rule I've gone by to think about these hunting matters is 1000 foot-pounds/1356 joules of energy is needed. So, one can figure the ballistics from this to see, for instance, the maximum range for a given bullet/cartridge used for deer, elk, bear, etc.
Having said this, the energy of a 158 gr bullet @ 1700 f/s is right around 1000 ft-pounds, as can be seen from the Bullets By The Inch data for the 18" barrel.
So, the range, if one maintains the 1000 ft*lbs/1356 j rule is pretty close to muzzle. But, piggies may not be quite so large as a deer, but of course, they are quite tough, especially boars around the shoulders. Regarding the Bullets By The inch data, they list self defense loads, but you could substitute a hard cast lead bullet that you might want for pigs and obtain the same velocity.
I'd think a 357 rifle would be pretty good for close range work, assuming practice and reliable bullet placement, and that you could get a really hard, penetrating bullet that will stay together to do the job.
