I am amazed at how much difference is appearing in Omega stocks, now there is no doubt there will be some but if the recoil lug area is clean, the recoil lugs are seated all the way back toward the buttand you use between 25 and 30 inch pounds on the screws then at least some of the Omegas don't change POI more than 3/8 inch; then only time I ever had mine change much was when I miss read the gage and out 38 inch pounds on one of the screws and I have had that Z5 ever since wal-mart came out with them.
