you're completely fos. anyone taking cattle would do so at night and you couldn't hit him at 80 yds, much less 800 yds. In the lower 48 states, there's no place remote enough that you'd have any need of a survival rifle unless it was shtf. Why would YOU need to forage, and nobody else, does, hmm? If they do, plenty of them will shoot you on sight and it only takes one. The 308 can has to be so big and heavy (to truly suppress the subsonic load waf) that the gun becomes as bipod-only clunk. It's nearly that already and when you add 1.5 lbs and 10" of can to the muzzle, it's like having a 32" barreled shotgun. WAY too long. Classic dunning-kruger effect. You think everyone else is as dumb as you are.
