For shooting pigs, you need a bullet that will expand readily, but hold together and penetrate reliably. They aren't really that much different from deer. Any good deer bullet will work fine on pigs.
I've had good luck with the .284" Hornady 139gr BtSpt "Interlok" bullets. Also, the flat-based version.
I shot a decent sized doe in my backyard with the 150gr Nosler BallisticTip in '10 and it seperated and didn't penetrate, but granted it was a frontal shot to deer with head-down and it hit the spine. Deer died, so it didn't do that badly. I was dissapointed in lack of penetration and that the bullet jacket seperated and core disintegrated. So, the 150gr Ballistic Tips may meet your criteria.
The Sierra 140's have been quite good, too.
The Nosler Partitions are superior but too expensive. Not needed on pigs or deer.
My favorite bullet for my 7-08 has been some cheap Winchester 150gr PowerPoints I got from MidwayUSA back in '05. The were cheap, ugly bullets but killed deer all out of proportion to "looks". Over 45.0gr of IMR4350, I got ~2,700fps and under 2moa accuracy. Every deer shot with them were bang-flops.
For bang for the buck, you can't go wrong with the Hornady 139 "Interloks".
I can't recommend the 139gr SST's however. I had a box of them I bought back in '05. I shot 6 deer with them. 5 were chest/lung shots and they all ran off, no blood trail,either. The one I did kill was a downward frontal spine shot (14' high in ladder stand over food plot). Bullet did not expand at all. 1/4" hole through deer's spine, chest and out bottom of chest. Others have reported "blow up's" with same bullets, however.... So I say avoid them due to inconsistency.
Where are you finding pigs near Calhoun Co. Al ???
I grew up in Anniston. A few deer in Talladega National Forrest, better turkey hunting, but still not "good"...
I killed my first deer off of Hillabee Creek, off McIntosh Road, adjacent to National Forrest.
Nothing like the deer hunting I have down here in mid west Georgia... Got 4 in my backyard this year...
Have to drive to east GA (Savannah River area) or South GA (Albany area, excuse me... All-Benny...!) to find any pigs... but I do have a ham left in the freezer from one I got last winter...
besides, I had 12 turkeys in the backyard yesterday morning.
I haven't hunted the Talladega NF in 30+yrs... and don't intend to. Too many people and not enough game... just old-growth pine trees... but it is pretty, though!!!
