Went out this a.m. to finalize the sighting in for an upcoming chuck hunt next week. I had recently bought a new Weaver 8-32 for the 20 Tac. Started out shooting a 3/8" group at 200 yards with said combination. Put the gun in its case, as I wanted to shoot my 223 (cap was on turret.) The gun shot way left so I moved up to shoot at 100 yards. It was 4 1/2" left at 100 yards and the windage was not responding as it should. Anyway it had less than 50 rounds on top of the TAC, so the scope is going back. We will see how Natchez handles this. That is two Weavers that I had purchased that would not hold zero.
