I had the Sako Tecomate in 270 wsm which is pretty much the same rifle. Sako A7 in a Bell and Carlson stock. It would shoot and hold 3/4 MOA out to 700 yards with factory ammo. I later sold it and had a custom rifle built in 270 Weatherby. The guy I sold it to loves it and I keep kicking myself in the butt for getting rid of it. I keep looking at the same rifle in 300 win mag but may get rid of the 270 Weatherby and have Georgia Precision build me one in 300 win mag. I think you would like it and be satisfied with the rifle.
Good luck either way.
