never set the preload so low. NEVER at .020 from bottomed out tsk
All the instructions I've seen show from .020 tp .050 preload max, not .150 + preload twocents
I use from 1/4 to 1/3 turn preload depending if the adjusters are 3/8x24 thread with 1/3 turn or 1/4 turn with 7/16x20 threads with a 1/4 turn HOT up especially with aluminum heads scope


Not going to argue, it works GREAT !!!! smile
