I have a Mountain LSS in .260. Mounted a Zeiss Diavari C 3 x 9 on it. I have put about 20 rounds through it and am getting 1 - 1.5 inch groups at 100. It will definitely do better, most of my shooting was to sight in the scope and break in the barrel. I am not sure I will ever be able to realize the full potential of the rifle with a 3 x9 scope. In my experience, I have only been able to get really small groups with higher power scopes. I bought this gun to be a light weight whitetail rifle for shots under 250 yards. It is perfect for that purpose, they are really nice guns. Everyone that sees the rifle, wants to handle it. I know two other people that have the Mountain in 7-08, good choice.
