Comp Pro mag lifters

..... The new lifter instructions are recommending 1/8 turn. By my math that is .00625” of preload. Is my math off? Or is that right? Seems like next to nothing for preload. Is there something in how the lifter works that’s different from the others?

Bingo! Comp's Pro-Magnums are a different animal and call for (IIRC) .002-.004 warm preload. You don't set them the same way as traditional-style lifters...
