I am in the same boat. I started with a 700 ADL in 308. I started with reloading. That made a big difference, both in group size and cost. With Federal Gold Metal Match my best group was 5/8" with my average being 7/8" at $23 a box. With hand loads I haven't shot as much yet, but it is looking very promising. So far I am averaging better than 1/2" @ 100 at $10 a box. After decent glass on top I felt that the plastic stock was the weakest link in my set-up. My Bell & Carlson A2 Tactical Medalist should be here tommorow. Hopefully that is money well spent.
Have you made any changes yet? What kind of results are you getting?
