[QUOTE="Pdvdh, post: 1182902, member: 4191"] I tried 26.2 to 27.2 grains Varget behind a 60gr Vmax. After I was found good accuracy in 26.8 to 27.0 grain range, I chronographed 50-60 rounds in varying temperatures. More so than temperature sensitivity (MV variation with temperature change), my disappointment with Varget was the high ES even at the same temperature. A lot of my chronograph data was collected with 26.7 and 26.8gr Varget, Fed 205 primers, and 60gr Hornady Vmax. I also tried Hodgdon BC-L(2) and again quite a bit of ES/SD, although better than with Varget. Last powder I tried was Hodgdon Benchmark. That was the best of the three. But still obtain a few outliers that product ES up to 50-60fps. I run a triplicate chronograph setup. I obtain four recorded velocities for each bullet fired. The chronograph data is solid. I get good accuracy from all three powders out to 300yds. Just much larger ES/SD than I experience in 280 A.I., 7mm Rem Mag, 300 Win Mag, etc... [/QUOTE]
