I use that mount on my .308 with a 1.93" center line.
Not the lightest mount in the world but the scope isn't lightweight either, 3 pounds scope and mount.
All of my scopes are centered in the mount and the eye piece is over the charging handle, plenty of room to move it front or back if needed.
I use a bipod with rear bag or tripod to level the rifle.
I have a small level but this isn't much and fits in the pic rail.

I use the Wheeler Fat wrench as well on mounts and such, I use it at work more than on gun stuff though.
I have a plumb line on the wall of my bench that I use to verify it's level.
Using a bipod and a rear bag to level it I place the butt against the wall behind the line and shine a light down the front, adjust the diopter to focus the reticle and see if it lines up.
Then I just move the upper to a tripod, readjust the diopter and do a quick through the barrel bore sight.
