I had a Sako Finnlight in 270 WSM and it was the worst shooting gun I have ever owned (I've owned over twenty five centerfire). The gun itself was absolutely flawless and I loved the hell out of it but it was simply not an accurate gun. Groups ran around 2" with just about every load I assembled. I tried 130g & 140g bal. tip, SST, hotcore, partition, sierra gameking, and accubond over five different powders. I even tried some ancient 150 grain silvertips which turned out to be one of the better loads. I had it to my smith (Bill Leeper) to check the barrel for flaws or potential bedding issues I may have missed and he said it looked fine and the barrel was one of the better factory barrels he had seen. It also, like most wsm's, fed poorly with the bolt often over-riding the next cartridge. The A7 should not have that problem I think it is a straight stack mag. I had two options....send it back to the retards at stoeger or sell it. I sold it. Funny..... 1600$ for two inch groups and the 500$ .300 rem sps that I bought to replace it shoots honest 1/2 inch groups with the SECOND handload I tried. Go figure. I can honestly say I am the only guy that I am aware of who has had a bum sako. Most are deadly. I loved the stock and currently have a mcmillan hunter (sako 75 replica) on order for my .300 rem sps.
Just my experience.
