[QUOTE="Ballistic64, post: 183222, member: 3401"] Fred at SSS also made a post about another contributing factor to Savage hard bolt lift is the way Savage cuts the lug ramps in the reciever. "Another geometry problem is that the lead-in ramps and the primary extraction are not synchronized, but are actually in conflict with one another. When we true an action, it consists of much more than just machining a few mating surfaces. First the lead-in angles (the ramps that lead into the lug seats) are re-cut to a true helical cam. The factory cuts are made with an end-mill, and are not helical. A helical cam is like a spiral staircase, and I have developed special tooling to precisely cut the lead-in angles to engage the whole width of the bolt lugs." [/QUOTE]
