Sako S20?

[Hoss50]

Range report. I have been getting .5moa type groups with 208gr Berger LRHT.

I am planning to shoot this rifle in a PRS type match for my first go at something like this in March. I don't want to burn up all my Berger so I have some Hornady 208gr ELDM sitting here that I didn't plan to use. So I loaded up the slow load I have found with the Bergers at about 2720fps, except with the ELDM.

First group I shot was the best group I have ever shot. I usually shoot 3 round groups, but I load up 4 rounds of each powder charge in case I know I pull a shot. I shot 3 rounds and knew I didn't pull any, but sent the 4th just so I had the brass back to load. I think I am OK with the result.

4 rounds at 100 yards.

Impressive!! I have a bunch of the 208 A-Max bullets on the shelf, I guess I need to work up a load!

I have one in 6.5 PRC and am very satisfied.

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.

I'm doing the same, s20 7mm rm. I can't get past 2800 fps with a 162g eld-x. Using 60.4 grains of imr4831. which is almost 200fps below book velocity...All of my tolerances are very tight. all chrono within 10fps but can't get the speed...
