I also have a Sako Finnlight in .300 WSM
I shoot Federal Premium ammo loaded with 180 grain Barnes MRX's. No problem keeping groups under a inch with this ammo. Never needed that last cartridge in the clip, but plan on checking it. Feeds flawlessly. I have no problem with the stock. Fits me perfectly and does the job. I have a Swaro PH 3-12x50 with TDS in Conetrol mounts. Weight is 7# 12 oz.
