Definetly a sub MOA grouping. The tanned square stickers are 17×17 mm as a reference, so I’d say the group is about 10-12 mm. 5 shots of 308, but it looks like 3, from the owner of the rifle.
These were shot at 300 meters, and sub-MOA. The recoil was relatively mild, but don’t have your nose too close to the scope if you’re not holding the rifle tight. Only 3 shots on this picture, but this performance was repeatable. I guess the factor which adds the most uncertainty is the shooter, not the system or the factory load.
