I'm in Florida, but have done a fair amount of hunting in southern GA. I have hunted hogs a BUNCH with an AR-15 using 50gr Remington PSP bullets. I've honestly lost count how many one shot kills on hogs at 100 Yds or less I've taken. Most of the time they drop where they stand, at worst, I've had them go 30 or so Yds and I lost one in a swamp. These hogs range in size from 80-200 lbs.
I've also taken a few southern deer with the same load. Probably 4 or 5 and they were all one shot kills too. The deer here in the south are kinda small so this cartridge combo is enough if you do your part. I will say, my favorite rifle for southern deer is a .243 with 95 Gr Nosler SSTs.
I'd recommend the .357 because I've had experience with it hunting. Never used a .45 ACP for hunting (have shot a hog with a .40 Glock 27 once). When I was younger I carried a S&W Mod 65 4" .357 with 158 Gr lead SWC handloads pushed pretty hard with H110. These rounds really thumped the southern deer and hogs.
So my opinion is, you'll be fine with what you got. Shot placement and keeping range to target in mind and you'll do fine.
