So, havent seen many threads on this subject, so I'm curious... are there many fans of the 308 AR's?
I picked up an Armalite AR-10T (24" SS bbl) a few weeks ago, and while it's a bit of a challenge to find a good load for, it's an absolute blast to shoot. Today, I tested some handloads and unfortunately, the best shooters for my rifle was Nosler Ballistic Tip 165's. I say unfortunately because the Nos BT's are (in my mind) too expensive for target shooting, and too worthless for Alaska hunting (not that I'd tote this particular AR very far in the woods anyway). Today with a load of 43.0 Varget I got .75" 5 round groups at 100 and .75 5 round groups at 200
My friend has a DPMS LR-308 with a 20" bbl- A2 setup which seems to shoot just about anything less than an inch.
Nevertheless, it's still a LOT of fun to shoot off the bench with very little recoil, and the legs to get pretty far. I've shot 3 sessions at the range with it, and shot 180 rounds the first session, 47 the next, and 150 the third, with absolutely no effects of recoil (there really isn't any).
So, are these catching on? Seems to me with the right setup (barrel length etc) that they'd be a very useful rifle for hunting most things here.
