My only reason for swapping scope bases was that I wanted a 20 moa rail. I've taken the rifle out to 1,000 yards, but at no point was I ever impressed with the group sizes.

I have not played with the torque on the front action screw. I've got a torque wrench so any suggestions there would be great.

When shooting, I'm either prone in the grass off a bipod, or sitting at a bench off a bipod.
