.308 winchester is OK for long range shooting. It definitely works out to 1,000 yards and beyond occasionally but there are many rounds that are superior. For example, I was never a big fan of the .243 winchester until I came to find that it is actually superior to the .308 for long range precision marksmanship. 7 mm projectiles tend to offer superior ballistic coefficients and better long range performance to .308 as well. Then there’s the mighty .338 lapua or the 338/378 weatherby magnum both of which are readily available to the civillian marksman and fully capable of hitting targets very hard beyond 1 mile with the right optic set up and shooter.
Rural Alaskans luv the old military guns, so when all the new calibers came out for ARs, well it’s second nature. I used a 6.8 for a couple years, then Armalite 338 fed, but it was just too heavy to lug around. Picked up a 308 SCAR a year back and it’s killed a bunch of caribou, a few black bear, and my nephew even killed a grizzly bear with that SCAR, 250 yards away moving out too; magazines are sweet for when ya miss the first shot or two. Anyway, I load 165 A-FRames & 168 TTSX’s with RL-15, TAC, and 4064 if I have to. I only load 43 grains or less, chrono’s right under 2500 and that’ll kill anything I’m shooting at. Here’s the problem, just look around for some RL-15 or TAC; non-existent. I see primers, can mail in bullets, but there ain’t powder anywhere right now. Something ain’t right?
