[QUOTE="KSAv8r, post: 2784966, member: 86098"] I'm currently doing load development on a Sako S20 with 20" barrel in 7mm Rem Mag using the new Hornady 150gr CX bullets with Hornady's recommended seating of 3.250" COL. The action and trigger are very smooth as expected from Sako and Tikka. Accuracy is good (around plus or minus 1/2 MOA @ 100 yards) using 59.5 grains of IMR 4831 with Rem 9 1/2 LRM primers showing 2810 fps on the LabRadar. Took it to 62.0 grains of IMR 4831 and did not show pressure signs. However, this only took it to 2905 fps and opened up the group size to about 2 MOA. Going to do some work on varying seating depth at this higher charge weight but will likely stay where it likes it at 59.5 grains to extend the barrel life. If I had any concern with the Sako S20, it would be with their composite stock and will likely be one of the first items to be upgraded. [/QUOTE]
