And there is a reason the is millitary gives the 308 a max executive range of 650. And we'll I don't want to be hoping that the round has the power there to knock it down. The ballistics say it all. 308 is a great round from 1-400 but that is where you need the bigger case and energy that is carried out at that distance. But it is a preference thing. I Load my own ammo. And sling a 150sst in 30-06 with 54gr of varget that will group in a pie plate at 900. Farthest I have shot the rounds as of yet. Get what you want and will be happy with. Go with friends and shoot all the aforementioned calibersa and see what you like the most.
