I used it one time in 6.5 creedmoor, it seemed to be good ammo and very accurate. I've read really good reviews on it but haven't used it enough to back up those reviews. I'd buy one box if it works great buy more if not you know better next time. Personally seems like quality ammo from my small experience and reviews. Hope this helps.

I have never used it personally bit all the reviews I've looked up customers say its pretty high quality stuff.
From buds own sight-----5 star 270 Winchester review, "Got a Sako S20, ammo is hard to find. Thought I would give the Sako factory stuff a shot. 3 shots at 100 yards had 3 holes touching each other. The gun is subMOA with Browning BXR, but this stuff shot even tighter groups."

5 star 6.5 Creedmoor, "Just got back from the range after shooting the Sako Super Hammerhead in my Savage 6.5 creedmoor. This is the most accurate factory ammo I have used. First two shots at 100yds cut the same hole, the third 1/2" to the left. Good stuff."

The other reviews I've read on the internet all seem to echo this as well.
