Wow. Just wow.
After reading about them for months and purposely waiting for the Gen 2 to come out, I picked up a .308. I was a bit disappointed at first: The hand guard was off center, various screws were loose, the muzzle brake was off center. So I took her completely apart and reassembled it in perfect alignment, torque'ing everything for precision in the process. Today was its first trip to the range. I'm thoroughly impressed. After sighting in at 100 yards and simultaneously breaking in the barrel by solvent/patch punching every 5 shots, she was ready for a little testing of preferred rounds.
The below target shows how barrels develop a preference for a given ammunition. The target is at 200 yards and each group is 10 rounds (a full mag). The bulls-eye group was shot with Federal Gold Medal Match (BTHP) 168gr. The group in the upper right area was shot with Hornady BTHP Match 168gr. I cleaned the barrel between these two tests and allowed it to fully cool. No adjustment to the scope was made because, clearly, it's dialed in. I cleaned and re-shot a 10 shot group of the Federals on a fresh target just to make sure everything was still correct and that something had not screwed up between tests. Results were the same, 10 shots inside an inch.
I have never seen an ammo preference this severe before. But wow, an out-of-the-box tack driver. I'm going to wear this thing out.
