I've only had then to the range once. Working up to JB's 2650 FPS load with my slightly slower-burning lot of Varget. I'm at 2600 with 62 grains (23.5" barrel) accuracy seems good in my small sample and POI is the same as the 250 AB thought these are a fair bit longer - likely a better BC than the AB but Nosler list the same BC for them both. Probably an error since in every other bullet diameter/weight combination for which Nosler makes both and E-Tip and a BT or AB, the E-Tip is shown with a higher BC. My guess is they were just making it easy without testing it yet.
