308WIN,
The real world tests with the 155 AMAX in my rifle were .474 and the 155 SCENAR was .499 Both were tested with a 308 win, 24" bbl, 11.25x. The AMAX was 2898 FPS and the SCENAR was 2910 FPS. Both were fired at 100, 300, 600,800, 1000 yards. They both followed the G1 curve VERY closly with those BC's. The AMAX's were by far the most accurate at 1k in my rig. The best I did with the SCENAR was 5" and the worst with the AMAX was 4.5" There was no measurable wind. The best group was 3.5" Intersting fact was that the best the AMAX would do at 600 yards was 6". Those BC's will be higher or lower depending on the velocity and twist you are using.
