Deer & Elk season starts up here in MT this coming Saturday and due to poor planning and some bad luck on my part I don't have my favorite hunting rifle available this weekend (Kimber Talkeetna in .375 H&H). Since we can now use suppressors for big game hunting up here I decided to try some factory loads in my AI AW chambered for .308 Win. I shot a 5-round group at 100 yards using Black Hills 155gr A-MAX ammuniton and the accuracy was outstanding. The scope is zeroed at 100 yards for 165 to 168gr ammunition so the group was 5" higher than the POA.
I don't want to use an A-MAX bullet for hunting so I figured I'd try some Federal Premium Vital-Shok Trophy Copper 165gr which was also outstanding. I shot a 6-round group last week without cleaning after the Black Hills load and then shot this 5-round group last night in under a minute prone off a bipod and no rear bag (hunting scenario). The 6-round group last week was good but the first couple of shots opened the group up a bit. The target below indicates that the bore has settled down since I haven't cleaned the barrel for a while. I was very impressed with the accuracy of this factory load and the numbers from the chronograph show good quality control. Federal lists MV at 2,700 fps and the average of five rounds was just a few fps slower from my 26" barrel.
I recovered two bullets from the sand backstop and they look great. Weight retention was right at 99.4% with > 2X expansion.
Here's the rifle ...
