When you start taking game with it, let us know how it does. What length barrel? The only thing that has kept me from building one of my own is the cartridge's need for longer barrels.Are you 100% sold on the 308? I went through the same thing several months back, and I just decided I didn't want to lug around a heavy 308 all the time in the woods. And I've never cared for the 308 recoil when hunting pigs where you can get multiple shot opportunities.
I started looking at the 6.8 and 6.5 Grendel, and I chose the 6.5 after shooting them side by side. Lighter weight, less recoil, it'll take any game in GA that the 308 will, and you can buy cheap Wolf ammo for plinking. All my 308s are gone except one.
If you're 100% sold on 308, then I'd look at the AP as others have suggested, or maybe an Armalite for mid range cost. I'd stay away from the DPMS, and I haven't really kept up with the PSA, but they're generally hit or miss.
