I know hornady says data is interchangeable but I do wonder. I think it's a hit and miss with what caliber. My 300 win mag using 165gr GMX got high pressure at 77grs with RL22. Current load not is 75grs and accurate. However, using 130 gr GMX in my 270 win with no problems using same data.

OAL:3.320 MV over the screens avg 2830-2860 fps depending on powder charge. Accuracy is 7/8"-1.25" . So far, this load has worked well at the range. Haven't taken any game with it yet, but feel very confident with it.
