I own several Sako rifles. A couple of 85s and an A7 Roughtech Range with Atlasworks bolt shroud, handle and bottom metal in 300 WM. AISC bottom Metal on the way. All three of them shoot like that. They are half moa guns with just about anything you feed them. My 375 H&H is the only gun of that caliber I have ever been able to free hand off a bag on a bench. The stock ergonomics are incredible. Glad you like it! Look into the aftermarket Atlasworks parts. They turn the A7 into a premium gun. You could not build one close to it for the price. I like the A7 better than the S20. Atlasworks already makes AISC bottom Metal for the rifle you have. Is yours a sporter or the heavy barrel version?
