I'd Pick up the .308 every time. Ammo availability is priority one and the .308 wins hands down. Everything from factory loaded match ammo to 180 nosler partitions. I use the 168 gn. Gold medal match (available at cheaper than dirt for 22$ a box of twenty) and average five shot 2" groups at 500 yds. The rifle is a howa 20" fluted barrel with a 4 x 14 zeiss scope. This weapon system has accounted for over 50 hogs taken off our ranch in the last 6 months. These shots were at ranges between 100 and 800 yds. I highly recommend Ivey scope mounts as they have worked perfectly for me and have 150 minutes of elevation built into them.
