Like most I wanted an accurate load but with good velocity. In the past I was able to get 7 WSM to shoot quite well. Then the phase hit where I was having trouble finding a load that would give me both accuracy & velocity. None of the usual powders were giving me the results I was looking for. This new rifle was showing pressure signs with early with the "favorite" powders. I had a 1 lb. of Win. Supreme 780 on the shelf so I decided to try it. I am very glad I did. good accuracy with a small (5 shot) sample of 3008 fps. I need to do more testing as 5 rds. isn't much but it is a step in the right direction. I tried both Fed. 215 Mag Match & standard Fed. 210's. This rifle liked the FGMM primers best.
