The scope isn't bottomed out in the tube but from looking at the rear you don't have much room to move it forward without the adjustment ring hitting the mount bolt.
My 99s always shoot high if I zero them on the bore sighter. I just set them 2 bars low now and it works pretty well.
Sounds like you have a winner then!
The overal measurment of the scope is 10 1/2 inches which means I have one inch in the tube. As long as the rifle performs that would be OK?
