Use a brush and solvent and clean out the chamber area of your rifle real well. Also, strip and clean bolt, bolt face etc and trigger group. Now cycle some factory loads, if they are tight, send gun to Sako for repair. Factory ammo should go in and out slick and smooth. If not, something is wrong with the gun.
If is very hard to diagnose the hard to extract after firing issue until after the gun is feeding and extracting unfired factory ammo properly. From the picture I would not say those rounds are over pressure, or at least not by much. Primers are not flattened, no cratering and just the odd one with extractor marks. Federal is VERY soft brass so extractor marks on it is pretty common.
