Did you include any cast in the stock ?
I find when standing it's better when the scope comes to the eye rather than having to take your eye to the scope . I had an Ev stock that I cut through the pistol grip with a chop saw to achieve this . It made such a difference that it's something I would look for in any rifle I own.
Off subject a bit , I have been trying HFT at a local club and have been enjoying it . On the course I have been adjusting my butt plate and hamster for each lane , is this allowed?
About as much use at field target , as a life guard at the Olympic swimming pool.
