Here's something to chew on. My 338 RUM has 4555 pounds of energy at the muzzle and still has 2785 at 400 yds. Yes accuracy is very important but at longer distances the more shock the more blood vessels ruptured and a bigger blood trail assuming there is an exit wound. That is unless a perfect head or neck shot can be made. I'm not bashing a 308 because I've got 2 of them and still hunt with them. But at shorter distances I use a 45-70 and the 45-70 can kill any game in north america. However it isn't ideal for long shots because it is a slow moving round. The bottom line is shoot what you want, drive what you want, eat what you want.its personal preference.
