I have recently mounted a Leupold Vari-X III 6.5X-20X40mm EFR on an Anschutz 54.18 MSR using Burris Signature Zee Weaver-Style Rings on Weaver Grand Slam Top-Mount Bases. Using the neutral offset inserts I was surprised that I sighted in with windage turret almost fully to left. I realise I can correct this with Pos-Align Offset Insert Kit but it seems a very extreme starting point.
