After hauling my Remington 700 SPS stainless in 270 WSM with a Leupold VX-L 3.5-10x50mm through the woods in Eastern Oklahoma / Western Arkansas, I have a better idea of what I think would work well for hogs in that area.
According to our host, they can get as big as 350lbs, but that's exceedingly rare. More like 150-200lbs is much more common. 200yds would be considered a very long shot. 100yds being much more common.
Figure roughly 30-30 Winchester class cartridge at minimum.
I was looking at AR-15 based cartridges, such as 6.8 SPC, 6.5 Grendel, 300 Whisper, 300 RAR, etc -- but they all seem to be on the low-end power-wise, especially with a 16"-18" bbl.
I was toying with a 16" AR-10, but you're at ~9lbs right out of the gate.
Seems like the Remington Model 750 carbine would be darned-near perfect. Can't decide between 308 or 30-06 though.
Any other options I'm overlooking?
